Zucchini is more resistant to low temperature, so it can not only be planted in spring, but also can be planted in autumn, but the temperature in the summer season is too high, the sunshine is long, the amount of female flower is small, and it is difficult to bear the complete fruit, and the seed is planted before and after the "Liaoqiu". The situation is strong, the number of female flowers and the rate of results are high, but the autumn planting of zucchini has a short period of collecting melons, serious viral diseases, and low yield. It is necessary to strengthen prevention and treatment of diseases. 1. Preparation before planting Select winter leisure land that is not heavy. Before winter, it will be ploughed and sun-dried. After the spring is frozen, it will be planted in the middle and late March, and planted in late March or early April. The 畦 type specification is: high ridge film cultivation, ridge surface 50cm, ridge spacing 70cm. Average row spacing 60cm, plant spacing 60cm, single row planted in the ridge pre-face, 1840 plants per mu. Before planting, apply 1OOOOkg of manure, or 5m3 of decomposed ring fertilizer, 30kg of phosphate fertilizer. When applying phlegm, if the sensation is not good, water can be poured once in 10 days before planting, and water should be poured when planting, first open the hole to put seedlings, then Watering. If it is planted early (mid-March). Can be buckled plastic small arch, covered with grass at night, no ventilation within 5 days, after survival, can be gradually ventilated around noon. 2. Management after colonization (1) Management of fertilizer and water In the process of growth and development, if the management is improper, it will cause various problems, such as seedling stage and the first female flower fruiting period. If the nitrogen fertilizer and water are too much, the plant will grow, the differentiation of the female flower and the fruit setting. It will be affected, not the female flower appears late, that is, the phenomenon of melon production; on the contrary, the early fruit period leaves too much melon and the harvest is not timely, the reproductive growth is dominant, it will produce the phenomenon of falling, so that the poor birth, resulting in Early aging, disease is clustered. The basic principle of field management of zucchini is the same as that of cucumber, which can be referred to. After the summer squash is slowed down, it should be combined with top dressing to pour a water (to be darkly poured) to promote the development of the roots, and to promote the cockroaches, laying a good foundation for many results. This water is especially important for short-lived zucchini. After the seedlings, the morning and evening of the melon watering is the most important. It will be crazy (running) early, and it will fall when it is late. It is more appropriate to pour the melon water when sitting on the melon, and the number of watering and watering will increase gradually. (2) Protecting the first melon The first melon is the center of pre-management and the key to capturing high yields. The stems and leaves of the zucchini grow rapidly under moderate temperature conditions, with excessive water, long stems and leaves, and atrophy of the fruit, resulting in a large number of "melons". Therefore, before the first melon is set, no water is poured, and the cockroaches are kept, so that the fruit is fully developed, and the old vegetable farmer has the experience of “pour the melon without watering the flowersâ€. The specific management is that after 3 days of planting, the seedlings resume normal growth until the first melon is shaped, which is mainly to increase the ground temperature, control the watering, expand the root absorption range, promote root control, and facilitate the transformation of organic matter into fruits and control water. Also be flexible. If the water content of the 5cm under the surface of the flower is less than 20% (holding the soil sample, the hand soil is not agglomerated), it is necessary to open the water to meet the water needs. The key to the first melon is to carry out artificial pollination. Because of the low temperature in the early stage, the amount of flowers is small, and there are few insects, which is not conducive to pollination. Therefore, artificial pollination must be carried out, and “Tomato Spirit†or 2, 4-D painting should be carried out. . The specific method is: every day between 9-10 o'clock in the morning, take off the scattered male flowers, remove the corolla, apply the pollen on the head of the female flower, a male flower can give 3 female flowers, and the effect is not good. The concentration of "Tomato Spirit" is preferably 0.003%. The optimum concentration of 2.4-D is 0 002%-0. 003%, and the time between the base of the style and the base of the petal is painted with a brush. What is the first melon to be stereotyped? Generally, the young melon grows when the tea bowl is thick (8-10 cm in diameter). It is not advisable to turn the melon into water. (3) Other management Generally, the dwarf type does not need to be pruned, and the vine type needs to remove all the side branches in time, leaving only the main vines, and picking the heart when climbing the face. In addition, if the rain is forecast on the next day of pollination, the male flowers can be transplanted in water for cultivation one day before flowering, and the pollination will be carried out in the next rain. After pollination, the petals will be gathered and covered with leaves to prevent rain. The harvest of the zucchini should be timely to prevent falling, especially the root melon should be harvested early so as not to affect plant growth and later yield.
