Bai Lu Qiu Dong vegetables are good
White dew is the result of the drop in temperature and the condensation of water vapor on the ground or near objects. Therefore, white dew is a sign that the weather has turned cold. As the saying goes: "A cold autumn rain, ten autumn rain wear cotton." Bailu Solar Festival has less rainfall, more sunshine, more light, mild climate, and large temperature difference between day and night, which is very suitable for the growth of various vegetable crops. It is necessary to seize the favorable opportunity to plant good vegetables in autumn and winter and planting vegetables in autumn and winter, and also to do a good job in vegetable nursery work in overwintering areas.
Autumn sowing cabbage pay attention to pest prevention
The autumn sowing Chinese cabbage is in the rosette period. The early sowing cabbage has already reached the heart-wrapping period. The Chinese cabbage should be well managed in the cultivating tillage and weeding. After the seedlings are finished, they start to water and topdress, and they can take open holes or open ditch. Top dressing method, apply 300 kg of biological organic fertilizer per acre or 20 kg of nitrogen, phosphorus and potassium ternary compound fertilizer; it can also adopt the method of top dressing with water, topdressing NPK fertilizer and a full liquid fertilizer 8-10 kg per acre. Chinese cabbage is mainly used for watering topdressing to promote the heart and growth. Watering time should be controlled according to soil quality, weather conditions and plant growth, but the amount of water should not be too high for each time. The rosette period is a period in which pests and diseases occur more frequently. The focus is on the prevention and control of viral diseases, downy mildew, black rot, and aphids and greenworms. Strengthen field inspections on the disease and found that the central diseased plants are prevented and treated in time. Most of the insects are insects of the night moth, hiding in the daytime and harming them at night. If the spraying is not effective during the day, they should be applied only when the dew is not dry at night or in the morning. In recent years, there have been many occurrences of dry-heart disease in some plots. It is necessary to control the amount of nitrogen fertilizers, increase the application of phosphorus and potassium fertilizers, and reasonably water the plants, especially during the period from rosette stage to early balling stage.
Radish, carrots focus on moisture management
Various kinds of radish have successively transferred from the leaf growth phase to the breaking belly phase and the fleshy root growth phase. The water management in these two phases is different. In the leaf growth phase, the control of watering should be the main method. If the watering is too early, the leaves will be promoted. Overgrowth affects the growth of rhizomes. To break the belly stage, it is necessary to transfer water to the rhizomes at the right time, and watering should be done regularly to keep the soil moist, so that the roots can grow well. If the base fertilizer is used adequately, it is not necessary to top-dress fertilizers; Pest work. Carrots are still in the leaf growth stage, to control the watering, if there is no rain for a few days, the soil is dry, plants can be poured slowly when a small amount of water is poured, mainly for the cultivation of weeds and control locust work.
Autumn winter crops ensure the quality of planting
The greenhouse with good heat preservation can still plant such thermophilic crops as tomato, eggplant and sweet pepper. To fasten the shed film in advance, do a good job in the disinfection of greenhouses and soil, apply organic fertilizer as the base fertilizer, and apply 5,000 kg or more of high-quality organic fertilizer that is fully decomposed and crushed per acre; fertilize and finely prepare the soil within 10-15 days in advance; Doing ploughing, leveling, no light or darkness; making a sorghum or tile ridge higher than 15-20 centimeters above the ground, ridges and ridges suitable for sheds without drip irrigation facilities, digging a V-shaped watering ditch in the middle of the rake, It is convenient to adopt the watering method of dark irrigation under the membrane in winter. To ensure the quality of colonization, choose strong seedlings with uniform growth and size, and require suitable depth and density, with reasonable density. About 3,000 common tomato varieties and 2,200 cherry tomato varieties will be planted for 2-4 seedlings per plant to prepare seedlings. . Because of the higher temperature, the planting in the sunny afternoon is better, and sufficient water is poured in time.
After the planting of the sandy loam sheds, the saplings were re-watered 3-5 days after planting, and timely cultivating loose soil promoted the easing of seedlings.
Overwintering alfalfa and warm crops
In greenhouse cultivation, tomato, pepper, eggplant, and other crops grown in greenhouses with good insulation properties were raised in the middle of September. Greenhouse cucumbers and zucchini, which have moderate insulation properties, were raised in early September; greenhouse cucumbers and summer cucurbits with good insulation properties were raised in late September. Select good varieties with good cold resistance, low temperature and low light resistance, and continuous fruit setting ability under low temperature and low illumination conditions. Cucumber can be selected "Zhongnong 26"; eggplant "precocious Jingjie 6"; pumpkin can be selected "jinghu 12" or "jinghu 36" varieties. Use 50-hole or 72-hole plastic tray seedlings to prepare the substrate with peat, vermiculite, and perlite. You can also purchase prepared special substrates. Do seed treatment and prevention of tomato yellow leaf curl disease. Cucumber grafted seedlings, the best choice of dewaxing powder, a good flavor, "Northern agricultural bright anvil," brown seed pumpkin as a grafted rootstock.
Rapidly growing leafy vegetables in the field
Can be seeded rape, spinach, garland chrysanthemum, coriander, oil and wheat vegetables, fennel and cherry radish, small radish and other fast-growing vegetable crops, in the late September to early October harvest market, to meet the market demand before and after the National Day. It is necessary to finely prepare the soil, evenly sow the depth of soil, and ensure the soil moisture required for emergence.
Autumn greenhouse vegetables do a good job in management and harvesting
The greenhouse cucumbers have been harvested in the autumn, and the tomatoes are in the stage of fruit set and fruit enlargement. The eggplants and peppers cultivated in the summer are also in the fruit harvest period. Field management should be strengthened to promote the fruit with high rate of multi-crude products.

◆Adjust the suitable temperature, light and humidity The suitable temperature of thermophilic vegetables such as tomato is 23°C-28°C during the day and 15°C-18°C at night; the suitable temperature of cold vegetables like celery is 20°C-22°C during the nighttime. °C-12 °C; shade nets do not need to be covered to make crops as bright as possible; indoor air humidity is adjusted according to different crops; sweet peppers, cucumbers, and leafy vegetables are 60%-85%; tomato, eggplants are 45%-55% .
â—† Pruning in time to remove the old leaves, yellow leaves and lateral branches, favorable ventilation and light transmission and plant results. When the tomato grows to the ear, it picks up the heart as early as possible, generally leaving 3-4 spikes of fruit. Cucumbers, squash, etc. must be wrapped around the pods and vines to prolong the growth of the plants to produce more melons.
◆ Fruit management Tomatoes and eggplants can adopt bumblebee or pollinator-assisted pollination to increase fruit setting rate; when using conditioners to spray flower or decorate, “Feng Yielding Agent No. 2†and “Fructoin†should be selected to be safe for crops and not easy to appear. Malformed fruit products. Also sparsely remove excess fruit.
â—†Scientific watering and top-dressing watering topdressing according to weather conditions, soil conditions and plant growth to meet the needs of growth and development. The integration of water and fertilizer technology should be vigorously promoted, so that with the use of drip irrigation, the "Christmas tree" with nutritious and reasonable ratio can be quickly dissolved. Fertilizer is appropriate. The ratio of fertilization of different crops should be different. Tomatoes should be topped with a high-potassium content of 5-8 kg per acre with a nitrogen, phosphorus and potassium content of 16:8:34 during the fruit expansion period.
â—† Prevention and control of pests and diseases In particular, to prevent the occurrence of tomato yellow leaf curl virus disease, the entrance and outlet with a 50 mesh insect net seal, timely control of the damage of whitefly. After the rainfall and when the temperature is low, the tuyere is closed in time to avoid the formation of a low-temperature, high-humidity environment and to prevent the occurrence of tomato late blight and cucumber downy mildew.
â—† Harvest in time to prevent fruit falling in the early morning of the sunny day to harvest good quality, improve the quality of the renovation, the size of the fruit sold separately to increase the value of the goods.
Exposed ground beans and kidney beans harvested in time
The beans and juniper beans planted in the fall are harvested at a prosperous time, and they must be harvested in the best commodity period. Since the plants are lush, the weather is dry, and the amount of water evaporation is large, we must do watering and top dressing management. once. We must also do a good job of prevention and control of pests, locusts, rust, and other pests and diseases.
Autumn sowing winter garlic
Autumn sowing garlic in winter sowing in mid-September, to choose good quality, strong flavor purple skin garlic varieties. To fertilize the soil in advance, pay attention to the use of organic fertilizers that are fully decomposed and comminuted, and fine soil preparation; uniform sowing, consistent depth and depth, appropriate thickness of cover soil, and timely watering after sowing.
