Myth One: More fertilization, more output.
Many vegetable growers fertilize their greenhouses in a greenhouse, in order to produce more. In fact, vegetable fertilization is very easy to cause fertilizer. Solution: One is planted after 3 years of greenhouse, chicken, cow dung control within 2,500 kilograms, chemical fertilizer reduction of about 50%. Second, the whole salt concentration of the plot, pay attention to the application of cow dung, humic acid fertilizer and EM bacteria fertilizer, to improve soil carbon and nitrogen ratio, loose earth breathable, salt to reduce fertilizer harm. The third is to supplement boron, zinc, magnesium fertilizer, balance soil nutrition, in order to reduce investment, and strive for sustained high yield conditions.
Myth number two: stay seedlings, high yield.
Many vegetable growers tend to stay in the seedlings more often, thinking that the seedlings can be more productive. In fact, due to low temperature in winter, weak light, poor photosynthesis, less carbohydrate synthesis, so only reasonable density can yield. Solution: First, the overwintering of vegetables to reasonable planting as good. Second, in order to make full use of space, can take early planting, medium sparse plant, late Shing management methods, to shoots not crowding, to improve total production and total benefit.
Myth Three: High temperature, fast.
In fact, vegetables have a ceiling on temperature requirements, generally 25. High temperature, respiratory function, body movement, physiological activity disorder, plant length, nutrition and reproductive growth imbalance, yield will decline. Solution: First, the greenhouse set up two lanes, timely cooling. Second, according to a variety of vegetable growth period required temperature and the appropriate temperature of each organ management, to prevent the high temperature long vine.
