Reasonable fertilization: Due to the high temperature and high humidity in the greenhouse, the decomposition of organic fertilizer is fast, and the amount of nitrogen fertilizer is volatile. Fertilizer overage can easily cause fertilizer damage. Therefore, for greenhouses that have been continuously growing vegetables for more than three years, the amount of chicken manure and cow dung should be controlled within 2,500 kilograms per acre, and the amount of chemical fertilizer applied should be reduced by about 50%. At the same time, boron and zinc should be supplemented. , Magnesium and other micro-fertilizers to balance the nutrients in the soil.
Reasonable Leakage: It was determined that 50% of photosynthetic products were consumed by vegetative plants when 2 plants were planted per square metre, and 50% of photosynthetic products were used for fruit growth. If 4 plants are planted per square meter, vegetative bodies will consume 70 to 80% of photosynthate. Therefore, excessive dense planting leads to reduced yield and is prone to various bacterial diseases.
Reasonable temperature control: Many vegetable farmers mistakenly believe that when the temperature is high, the vegetables will grow faster. In fact, the maximum temperature requirement for most vegetables is generally 32°C. If the temperature is too high, the growth of young fruit will be inhibited, and the vegetative growth and reproductive growth of plants will also lose their balance, and the yield will not only increase, but will also decrease, and some varieties may even show only long vines and not long fruit.
Reasonable watering: Many farmers regardless of the seedling stage and the result period are fertilized with large amounts of water, making the fertilizer and water too large, causing disease, rot, rooting. Whether bio-fertilizers, organic fertilizers, or chemical fertilizers should be used to see seedling fertilizer, a reasonable amount, and timely cultivating loose soil after fertilizer and water. Avoid flooding, the time should be sunny from 10 am to 15 pm is appropriate to avoid the early morning and late evening, cloudy or not pouring water, snow and snow days bogey.
