Winter anti-zucchini short coarse melon

Zucchini melon strips are short and thick, which will seriously affect the commodity value of zucchini and reduce the income of vegetable farmers. It is suggested to prevent the occurrence of zucchini in winter.

In winter, the air temperature and ground temperature in the greenhouse were low, the light was weak, the photosynthetic efficiency of zucchini was low, and the nutrient accumulation of the plant was less. In addition, the root function of zucchini decreased, the absorption, transportation and utilization of fertilizer and water were blocked, and the flower bud differentiation of zucchini was poor, which led to the increase of short and coarse melon. In addition, if the concentration of vegetable farmers wiping melon medicine is too high and the time of wiping melon is too early, it is also easy to lead to abnormal development of melon strips, forming short coarse melons; leaving many melons, not thinning melons, the nutrition needed for the growth and development of melon strips is insufficient, which will hinder the normal growth of melon strips and form short coarse melons.

The measures to prevent zucchini short and coarse melon are as follows: one is to improve the environmental conditions in the greenhouse, zucchini enters the fruiting period, it is necessary to raise melon at high temperature, keep the greenhouse temperature about 25 ℃ during the day, enhance photosynthesis, accumulate photosynthate, and keep the temperature at 12 ℃ ~ 14 ℃ at night, so as to facilitate the transport of photosynthate to melon strips and promote the growth of melon strips. At the same time, it is necessary to pick leaves in time, improve ventilation and light transmission conditions between plant rows, and reduce nutrient consumption.

The second is to pay attention to topdressing. The combination of functional fertilizer and fully water-soluble fertilizer can raise roots, promote vines and improve plant growth. It is also necessary to supplement foliar fertilizer, improve leaf photosynthetic efficiency and delay senescence.

Third, pay attention to the concentration of gourd should not be too large, it should be tested first and then applied, and the time of wiping melon should be the day before the female flower blossoms or the morning of the day of flowering.
