In recent days, a vegetable farmer in Zhangxibao Township, Yongnian County, said that the zucchini is not sitting on melons and what measures should be taken?

Zucchini has a well-developed root system and is prone to grow. After prosperous growth, it is easy to cause trees not to stand melons or to melon melons, especially in the early stage of plant growth. In this case, many vegetable farmers rely on hormones for control. However, due to excessive use of hormones by some vegetable farmers, the zucchini leaves in the greenhouse show a “chicken claw” shape, and even “headless” phenomena occur frequently, which seriously inhibits the growth of zucchini and reduces the yield of zucchini. To this end, the author reminded the growers of zucchini: the use of hormones to regulate the growth of zucchini is feasible, but not too dependent. To cultivate zucchini strong trees, according to the growth habits of zucchini, regulate the temperature, humidity, timely fertilization, adequate watering, in order to control and prosper.

1. Temperature management is the first element of control. Zucchini squash during the early days of growth and development temperature of 18 °C -22 °C, night temperature of about 10 °C. If the daytime temperature is higher than 25°C, photosynthetic products will accumulate less and consume more, and the zucchini will prosper. Therefore, the management should pay attention to the regulation of the appropriate temperature, rather than warm the tree. The temperature control measure is to strengthen the ventilation, and do not close the front air outlet prematurely.

2. Avoid excessive soil moisture. After the jujube has been planted and cultivated, management should be based on controlling water and promoting roots. If the soil is not overwhelmed with drought, do not rush to water before squashing. Of course, if the plant is short of wilting, it should be poured with small water to ensure the normal growth of the plant, must not flood irrigation, resulting in plant growth. At the same time, the first amount of water after sitting on the zucchini root can not be too large, too large can cause the melon, which in turn leads to plant growth. In order to promote the smooth progress of reproductive growth, water can be poured by pouring small water.

3. Potassium control and potassium supplement in later period. After the zucchini enters the period of nectar, the demand for potassium is large. Therefore, the use of high-potassium fertilizers should also be taken into account during the fertilization, and excessive use of high-nitrogen fertilizers should not be used to prevent excessive plant growth resulting from excessive nitrogen fertilizer.

If hormone regulation is used, be careful not to use it excessively, especially paclobutrazol should not be used repeatedly. Generally, 5-7 days after the seedlings of the summer squash are sprayed, the plants are sprayed with 15% paclobutrazol for 1500 times, but do not spray the growth points.
