The key to the high yield of zucchini lies in the skillful management at flowering stage.

As the saying goes: a zucchini flower, only look at the melon on the vine. Zucchini can only be beneficial with high yield, and the number of sitting melons mainly depends on the quantity and quality of female flower pollination. According to the practical experience of cultivation, it is necessary to manage skillfully if you want to increase income, and the key point is to do a good job of artificial pollination and correct use of regulators in production.

First, careful management and protection, the implementation of artificial pollination.

The first flower of zucchini is usually female, and the second flower is usually male. Male and female flowers usually bloom at 4-6 o'clock in the morning, and male flowers can be seen to spread at 9-11:00 in the morning, which is the best time for pollination. When pollinating, you should first check whether the male flower produces pollen, touch the stamens of the male flower with your finger, and find that there is yellow powder on the fingertip, that is, mature pollen, and then take off the male flower, remove the petals, and rub gently against the stigma of the female flower to make the stigma pollinated evenly, otherwise it is easy to grow into a deformed melon.

Second, seize the right time and skillfully use regulators to wipe flowers.

In the air humidity is relatively high or there are no male flowers in the shed, and there are female flowers in the leaf axils of each vine, that is, a melon per leaf. At this point, it is necessary to use a regulator to promote melon sitting. At present, the most commonly used regulators for sitting melon are 2Jing 4murd or Baoguoning and so on.

To apply young melons with regulators, choose a sunny day from 9 to 10:00 in the morning. Specific method: after dipping the medicine with a brush, the first brush is quickly smeared on the stigma, and the second brush is gently daubed on the young melon body from the tail to the direction of the melon long handle. In addition, we should pay attention to: first, when the regulator is used, the concentration used is lower when the temperature is high, and the concentration ratio should be slightly larger when the temperature is low; second, the melon seedlings of zucchini are growing vigorously, and the concentration should be higher, and when the growth is weak, the concentration should be smaller. When using regulators, an appropriate amount of red, blue and black colors should be added as a colored sign to distinguish whether a flower can be dipped or not (a flower can only be smeared once, not repeated or more), and the best time to apply should be when the female flower is in bloom and the day before. What needs to be reminded is that it should not be carried out on rainy days and in the afternoon, because it is not effective, the fruit setting rate is too low, and it is particularly easy to grow into deformed melons.

Compared with Bao Guo Ning, vegetable farmers reported that the safety of Bao Guo Ning was better than that of 2mer 4mi D. On the one hand, it is not easy to cause toxicity and malformed melons; on the other hand, Baoguoning itself contains the drug ingredients for the prevention and treatment of Botrytis cinerea, which can not only promote the early sitting of flowers, but also prevent the occurrence of Botrytis cinerea.
