First, careful management and implementation of artificial pollination. The first flower of the zucchini is usually the female flower, the second flower is the male flower, the male and the female flower generally open at 4-6 o'clock in the morning, and the male flower can be seen at 9-11 o'clock in the morning. This is the best time for pollination. When pollinating, you should first check whether the male flower produces pollen. You can use your finger to wipe the stamen of the male flower and find that there is yellow powder on the tip of the finger, that is, mature pollen. Then remove the male flower, remove the petals, and gently rub against the stigma of the female flower. The stigma is evenly crushed, otherwise it will easily grow into a malformed melon. Grasp the right time, skillfully using conditioners to wipe flowers. Relative humidity in the air is relatively large or there is no male flower in the shed, and the leaf buds of each branch have female flowers. This situation is a leaf and a melon. At this point, it is necessary to use a conditioner to facilitate the sitting of the melon. Now commonly used melon conditioners are mainly 2,4-D or Baoguoning.

Use a conditioner to spread the young squash and apply it on sunny days from 9 to 10 am. Specific method: After using a brush to poke medicine, the first stroke is quickly applied on the stigma, and the second stroke is completed by gently applying a stroke to the melon in the direction of the tail of the young melon body. Also note: First, when the regulator is used, the concentration used when the temperature is high should be lower, and the concentration ratio should be slightly larger when the temperature is low; the second is that the melon quail of the summer squash grows vigorously, the drug concentration should be larger, and the growth is weak. The concentration should be smaller. When the regulator is used, appropriate amount of red, blue and black color should be added as a colored mark to distinguish between the flowers (a flower can only be applied once, and should not be repeated or applied). The best time to apply is Should be when the female flower is open and the day before, but it should be noted that it should not be carried out on rainy days and in the afternoon. This is because the effect is not good. Second, the fruit setting rate is too low. In addition, it is particularly prone to grow into malformed melons.

According to the use of vegetable farmers, Baoaning is safer than 2,4-D when compared with 2,4-D and Baoguoning. On the one hand, it is not prone to poisoning and deformed melons; on the other hand, Baoguoning itself contains medicinal ingredients for preventing and controlling gray mold, which not only promotes early flowering of melon plants but also controls the occurrence of gray mold.

Auxiliary Facilities

The greenhouse a filled with equipment like hydroponic, irrigation, auxiliary lighting ,temperature and humidity control and also may be automatically controlled by a computer to maximize potential growth.
Hydroponics can be used to make the most use of the interior space. The relatively closed environment of a greenhouse has its own unique management requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Most greenhouses use sprinklers or drip lines. Significant inputs of heat and light may be required, particularly with winter production of warm-weather vegetables.
