Vegetables are prosperous and long-lived, they must be rationally adjusted to promote high yield
Vegetable vigour and stem are different. Plant vigour is expressed as vigorous plant growth, thick stalks, and vegetative growth. However, the plants are characterized by long internodes, light green color, thin leaves, and weak overall growth. These two conditions are not conducive to reproductive growth.
Prevention measures
Partial application of nitrogen fertilizer caused the plants to flourish. This is a common problem in the management of vegetable farmers, especially after the application of base fertilizer with high nitrogen content, continue to add water-soluble fertilizer with high nitrogen content. Therefore, it is recommended that vegetable farmers reduce or even apply nitrogen-free fertilizers, such as spraying amino acid foliar fertilizer + potassium dihydrogen phosphate, continuous spraying 2 to 3 times, or flushing high-potassium-type water-soluble fertilizer containing amino acids to promote Nutrient absorption, improve plant growth. Then keep more fruits to improve plant growth. In the process of fruit development, it will compete for plant nutrition, so as to achieve the purpose of balanced plant growth.
What causes the plants to be long
First, the high temperature and low light environment can easily cause the plants to grow too long, and the shading net coverage time is too long. The correct approach is that the vegetable farmers should flexibly adjust the shading net coverage time according to weather conditions. Continuous overcast and rainy days in summer will also cause a high-temperature oligomerized environment. At this time, vegetable farmers are required to ventilate in time to reduce the temperature of the shed. In addition, the high night temperature is also the main reason for the plant's long standing. Specific cooling measures can reduce the temperature of the shed during the day and the cooling of watering. The second is longness caused by malnutrition. In this case, it is necessary to quickly replenish nutrition and promote plant growth; leave fruits late to avoid premature plant aging.
Human intervention must be timely
When the plant growth imbalance is not obvious, foliar fertilizers such as chitins, amino acids, potassium dihydrogen phosphate, and seaweed can be sprayed to regulate plant growth in both directions. If the imbalance is obvious, use wangwang medicines as early as possible, such as shunxi, chlormequat, auxin, chlorophyll, etc., mainly spray the plant growth points, pay attention not to repeat spraying.
