When the price of zucchini rose to 1.5 yuan/kg, many vegetable farmers planting zucchini did not laugh. Instead, they worried about the growth of the squash in the greenhouse.
According to Zhang Dejin’s introduction, the growth of the zucchini in the greenhouse is generally weak, which directly leads to less fruit set in the zucchini and slower rate of expansion, which affects the yield.
Where are the reasons for the weak growth of the zucchini in the current greenhouse?
According to reports, there are two main reasons for the above phenomenon:
1, the weather. The winter temperature is lower than in previous years. This is the personal experience of many vegetable farmers. However, it is precisely because of the influence of low temperature that the squash in the shed is problematic. With the continuous emergence of low-temperature and low-light sunshine conditions such as continuous cloudy days, the stronger growing zucchini plants are inevitably growing weaker.
2. The characteristics of zucchini affect the growth of the plants. Zucchini is the most prosperous of many vegetables, so it is also the most sprayed vegetable that controls Wang. However, its greatest feature is the continued fruiting, if too much fruit set will certainly lead to weak plants, especially in the low temperature conditions, the more obvious adverse phenomena.
In view of the weak growth of plants, Zhang Dejin believed that measures should be taken to strengthen plant insulation and rooting to restore plant growth.
1, strengthen the greenhouse insulation management. The temperature of the greenhouse suitable for the growth of zucchini is 26-28°C, but the temperature of the greenhouse under low temperature conditions is difficult to reach 25°C, which has great influence on the recovery of zucchini growth. Therefore, it is necessary to strengthen the temperature management of the greenhouse, and measures can be taken to protect the temperature of the greenhouse in the temperature range of 26-28°C suitable for the growth of the zucchini.
2. Culturing roots and rooting fertilizers promotes the restoration of plant growth. The weaker plant growth, the most fundamental reason is the low ground temperature, resulting in weakened root activity, and thus affect the plant growth, so to promote the restoration of root vitality can have a multiplier effect. It is recommended that vegetable farmers rush to apply bio-fertilizers (Wu Yi Duo, Bai Jing, etc.) to increase root vigor and restore plant growth when watering.
3, appropriate support trees. Since zucchini is a fruiting fruit, it is also one of the effective measures to reduce the burden on the plants. This can reduce nutrient consumption and allow the zucchini plants to resume production when they return to normal.
