Planting technology of zucchini in greenhouse

There are two planting methods of zucchini, one is large and small rows 80cm, small row 50cm, plant spacing 45cm 50cm; the other is equal row spacing planting, row spacing 60cm, plant spacing 50cm, planting 2000,200 plants per 666.7 square meters. If the temperature is low after planting, the small arch shed should be covered in time, and cold protection facilities such as grass canopy can be added if necessary.

1. Temperature management. The slow seedling stage after planting is not ventilated and sealed to increase the temperature to promote early rooting and slow seedling. During the slow seedling period, the greenhouse temperature should be kept at 25: 30 ℃ in daytime and 18: 20 ℃ at night. After slowing down the seedlings, the temperature should be lowered properly, and the greenhouse temperature should be controlled at 20: 25 ℃ in the daytime and 12: 15 ℃ at night, in order to promote the root development of the plant, which is beneficial to the differentiation of female flowers and early melon setting. After sitting melon, the temperature was properly increased, which was maintained at 22: 26 ℃ during the day and 15: 18 ℃ at night, in order to promote the expansion of melon. After entering the peak period of melon, the air temperature rises gradually, so it is necessary to gradually increase the ventilation volume and prolong the ventilation time, and the maximum temperature in the daytime should not exceed 30 ℃.

two。 Water it. Generally, it is not watered during the slow seedling period, and if it is not watered enough when planting, it can be watered once according to the soil moisture. Watering should be controlled in front of the root melon column after slowing down the seedling. When the root melon sits, water is watered once, and microbial fertilizer 20kg is applied every 667m2 with the water. After entering the peak period of melon, it should be watered in time according to the weather conditions and soil moisture, generally watering every 7-10 days, and applying urea or compound fertilizer 10-15kg each time. Watering should be carried out in the morning on a sunny day as far as possible. After watering, attention should be paid to ventilation and humidity reduction, and drip irrigation and dark irrigation under plastic film should be adopted as far as possible.

3. Plant adjustment and flower and fruit protection. Because dwarf and precocious varieties are selected in facility cultivation in spring, hanging vines and binding vines are generally not needed in the growth process, and old leaves, diseased leaves and yellow leaves should be picked in time in the growth process. Due to the low temperature in spring and the hindrance of facilities, there are few pollinating insects, and the parthenocarpy ability of zucchini is very poor, which often leads to flower drop or melons caused by poor pollination in spring. 30~40ppm 's anti-falling hormone can be used to smear the female flower stalk to protect fruit.

In order to increase the yield of zucchini, special planting liquid such as gold can be used, which is beneficial to more fruit sitting and less illness.
