Zucchini cultivation

Zucchini is more tolerant to low temperatures, so it can not only be planted in spring, but it can also be planted in the autumn. However, during the hot and summer season, the temperature is too high and the sunshine is long. The female flowers have less differentiation and it is difficult to produce complete fruits. Strong growth, both the number of female flowers and the rate of results are high, but the autumn harvest of pumpkins is short, the virus disease is serious, and the yield is not high. It is necessary to strengthen the prevention and pest management work.

1. The preparation before planting is to choose the winter resort that is not heavy, plow till the winter before winter, open the spring and freeze it, and then do the planting in the middle or late March, planting in late March or early April. The rake type specifications are: high ridge plastic film cultivation, ridge surface 50cm, ridge spacing 70cm, average spacing 60cm, plant spacing 60cm, single row planting on ridge pre-surface, 1840 acres planted.

Before planting, the manure and dry manure is 1OOOkg, or the decomposed manure is 5m3, and the phosphorus fertilizer is 30kg. When the plague is not good, the water can be poured 1 time before the planting, and the water is poured when the planting is completed. Watering. If you colonize early (in late March). The plastic arch can be buckled and the grass can be covered at night. It can be ventilated gradually before and after noon when it is not ventilated within 5 days.

2. Post-planting management

(1) Management of fertilizer and water During the growth and development of zucchini, if it is improperly managed, it will cause various problems, such as the seedling stage and the full fruit period of the first female flower. If the nitrogen fertilizer and water are too much, it will lead to plant growth, female flower differentiation and fruit setting. It will be affected, not when female flowers appear late, or when melons are produced. On the contrary, if the first fruit period is too much and the harvest is not timely, reproductive growth predominates, and it will produce a fall phenomenon, resulting in malnutrition, leading to malnutrition. Early aging, disease clusters.

The basic principles of field management of Zucchini are the same as those of cucumbers. After jujube seedlings are slowly rejuvenated, it should be combined with topdressing to pour water once (to be darkly poured) to promote the development of the roots and to encourage the crucian carp to lay a good foundation for multiple results. This water is particularly important for short-lived type squash.

After seedling emergence, the most critical factor is to wash the water sooner or later. If it is too early, it will go crazy (run), and it will fall later. It will be more appropriate if the water is poured after the water is poured. The number of watering and watering will gradually increase afterwards.

(2) Protecting the First Guava The first melon is the center of pre-management and the key to seizing high yields. The stems and leaves of zucchini grow rapidly under moderate temperature conditions, with excessive water content, long stems and leaves, and fruit shrinkage, resulting in a large number of "melonized melons." Therefore, before the first guava is set, it does not pour a large amount of water, grab the crickets, and make the fruit fully developed. The old vegetable farmers have the experience of “pouring water without watering the flowers”. The specific management is that after 3 days of planting, the seedlings return to normal growth, until the first cultivar is mainly multi-plankton, increase the ground temperature, control watering, expand the root absorption range, and promote root control, which is conducive to the conversion of organic matter into fruits, water control Also be flexible. If the 5cm water content below the table before the flower is less than 20% (hold the soil sample, extend the soil of the hand and do not clump), you must open the pot and pour the dark water to meet the root's need for moisture.

The key to maintaining the first melon is to conduct artificial pollination. Since the temperature in the early stage is low, the amount of flowers is small, and the number of insects is also small, which is not conducive to pollination, artificial pollination must be carried out and “tomato spirit” or 2,4-D paint must be performed. . The specific method is: Every day from 9 to 10 am, remove the male flowers, remove the corolla, and apply pollen to the female stigma. A male flower can grant 3 female flowers, but the effect is not good. The concentration of "tomato spirit" is preferably 0.003%. The optimum concentration of 2.4-D is between 0002% and 0.003%, and the best effect is to use the brush to coat the base of the style and the base of the petals.

How can the first melon be stereotyped? In general, young larvae grow to a thick teacup (diameter 8-1Ocm). It is not suitable to melon, and then watering.

(3) Other types of management Generally dwarf types do not have to be pruned. Invasive species need to be removed in time for all lateral branches, leaving only the main vine to be melon and picking up when they are quickly climbing.

In addition, if pollination is forecasted on the next day, the male flower will be inserted into the water for cultivation on the day before flowering. Pollination will be conducted in the next day's rain, and the petals will be collected after pollination, covered with leaves, and protected against rain.

The harvesting of squash should be timely to prevent falling pods, especially root melons should be harvested early so as not to affect plant growth and late yield.
