High-yielding Cultivation Measures of Spring Pepper
Choose a good seed
The cultivation of spring eel is in fact a precocious cultivation, and it is necessary to pay attention to the early maturity of the variety, taking into account the high yield and disease resistance. Suitable varieties include Hong Ying Da, Andalai, and the Holy Ark. In addition, the Bulgarian sharp pepper, the Su Jiao No. 5 and so on.
Soil fertigation
The quality of manure or compost of 10,000 kilograms was applied per acre, and 25 kilograms of urea, 50 kilograms of diammonium phosphate and 100-200 kilograms of cake were applied. These base fertilizers should be applied according to different colonization methods. Peppers can be planted flat or ridged. For the convenience of coating and watering, as well as to help improve the ground temperature, it is recommended to use ridges in the north-south direction. When ridges are planted to determine the ridge distance, they must be different for each cultivar, and the row spacing should be determined according to the opening angle of the cultivar used. In winter and spring, more than one plant should adopt the method of dense planting of one planting a pair of aphids. Large row spacing 55-60 cm, small row spacing 40-50 cm. When fertilizing, first spread the organic fertilizer on the ground and deep-dip twice to fully mix the fertilizer and the soil, then open the ditch by row spacing, apply the cake fertilizer and chemical fertilizer in the ditch, mix thoroughly with the soil, and then furrow on the ditch. The ridge height is 15-20 cm.
Scientific colonization
The time for planting was in late January, and planting must be done on a sunny day, and it is expected that after the planting, there will be consecutive sunny days. This will require more listening and watching more weather forecasts. Colonization should take place in the morning. When planting, press the hole about 33 cm to open the hole. About 4,000 holes per acre, 2 per hole, 8,000 per acre, with dense planting for early production. 2 strains in the same cave have the same size. When the seedlings were planted, they were poured with warm water (30-40°C) and the seedlings were placed.
Cultivate strong seedlings
The pepper seeds were soaked with 10% trisodium phosphate solution for 30 minutes before sowing. In order to prevent anthrax and bacterial spot disease, it can be pre-soaked with fresh water for 5-6 hours, then put in copper sulfate solution for 5 minutes, then washed with clean water and then germination. In order to cultivate strong seedlings, it is best to use electric heating lines for seedlings. When the seedlings grow two true leaves, the seedlings are subdivided once and the seedlings are transplanted into the nutrient pods, one for each worm, and placed on the electric wire nursery bed. The daytime temperature during the seedling period is maintained at 28-25°C.
Post-planting management
1. After the temperature management is planted, in order to promote easing seedlings, maintain a high temperature and high humidity environment, do not let the wind during the day and properly cover the grass hoe, so that maintain a higher temperature at night, after easing the seedlings, keep the temperature during the day 26-28 °C, After the temperature drops to 17-18°C in the afternoon, the temperature will rise 2-3°C after the temperature drops to 17-18°C. Afterwards, the temperature will gradually decrease. When the temperature is released on the second day, the temperature should be about 15°C. After entering spring, the temperature will gradually increase. Rising, we must pay attention to increase the ventilation, appropriate late grass cover, when the temperature is not less than grass cover temperature of 15 °C, the grass cover can not cover at night, but the grass clam can only be removed in mid-April to prevent the emergence of downside cold Other severe weather.
2, light management in winter light intensity is low, should ensure the temperature of the greenhouse, try to extend the lighting time, as early as late cover Ganoderma lucidum, so that the plant more visible light, while maintaining the film surface clean, improve light transmittance, in On the north side of the greenhouse, a light curtain can be placed to increase the light intensity. On a cloudy or snowy day, the light intensity is low, and the plant respiration is expensive. The extra-root fertilizer can be applied and 1% sugar water can be sprayed.
3, water and fertilizer management in the case of planting water pouring feet, to the first fruit (door pepper) before sitting generally do not water, after the seedlings in the slow seedling after the seedlings are mainly cultivator, the soil under the mulch can remain moist And good ventilation. When the seedlings are finished, they are poured with water once. At this time, the peppers have grown to a diameter of about 3 cm. Each acre is applied with 20 kg of ammonium sulfate and 10 kg of potassium sulfate. After each water or water is applied with water once, each mus of urea can be applied 10 kg or ammonium sulfate 10 kg. Carbon dioxide fertilization should also be performed.
4. Plants should be pruned in order to promote the results. In the method, the young fruit on the secondary branch of the main lateral branch grows to a diameter of 1 cm. After leaving 5 leaves in its upper part, it picks up the heart so that the nutrient is concentrated to supply the fruit. The leggy shoots appearing in the middle and later stages are removed promptly. .
5. The main diseases of insecticide-resistant pepper pests include powdery mildew, anthrax, soft rot, scab, and viral diseases. Insect pests mainly include aphids and whiteflies, and they should be given time to prevent and control them.
Timely harvest
After the planting, harvesting usually starts 40-50 days. Peppers and peppers should be harvested as early as possible to avoid affecting plant growth. When harvesting, it is best to cut fruit in order not to damage young shoots.
