In general, the price of vegetables planted in the off-season is relatively high, and the income of vegetable farmers is also relatively satisfactory. But how to maintain the normal growth of shed vegetables, extend the harvest period as much as possible to prevent premature aging? The author has the following experience:
Sakaguchi changes every year for high yield
If we want to make shed vegetables avoid premature aging and achieve high yields, the implementation of crop rotation is the most important means. It is best to change it every year. Including fruit and vegetables, leafy vegetables rotation, fruit and vegetable dishes and spicy sorghum (onions, garlic, leeks, etc.) rotation.
Balanced fertilization of shed vegetables is the most delicious
The production of shed vegetables should be scientific and balanced in fertilization. Organic fertilizer, chemical fertilizer, microbial fertilizer, and trace element fertilizer are all indispensable. General Mushi organic fertilizer 3 ~ 5 cubic meters, compound fertilizer 30 ~ 40 kg, microbial bacteria fertilizer 20 ~ 30 kg, trace element fertilizer 200 grams. Conditional soil testing can be done, do formula fertilization, do not single re-apply nitrogen fertilizer.
Watering but warm up first to warm up
In winter, the outside temperature is low, and the watering in the shed cannot be overworked. The amount of watering must not be too large. After the watering, the water in the shed cannot be lowered to release the air at a low temperature as soon as possible. After a period of time, the temperature should be raised before releasing the air to avoid the shed. Low temperatures and high humidity cause shed vegetables to cause rooting and lead to premature aging.
Removal of sick leaves leaves functional leaves
The removal of sick leaves at the bottom of the sheds in a timely manner will help reduce the spread of diseases and increase ventilation, but the amount of excision should be appropriate. Generally, 8 to 12 functional leaves are required for each fruit and vegetable plant.
Use good regulators
The production of shed vegetables is inseparable from the use of regulators. The use of regulators should not be too large, and should not be repeated (spray). It should be used when the flower buds are opened or fully opened, avoiding the use of sprays (sprays) to other parts of the shed. Causes phytotoxicity, making it difficult for shed vegetables to grow normally.
Early disease prevention and control save money and save trouble
Diseases and insect pests of shed vegetables should be guided by the principle of prevention, avoiding arbitrarily shortening the interval between medications and arbitrarily increasing the concentration of medications, and maintaining the relative cleanliness of shed vegetables, so that photosynthesis can be vigorous and lasting.
