1. Soil is the cornerstone of plant growth, and the quality of soil layer is directly related to the growth of crops. Because the roots must absorb water, nutrients, air and so on. In terms of soil, it is stipulated that the soil for planting vegetables should be water-locked, soil-consolidated, loose and breathable, and organic fertilizers and microbial fertilizers should be applied to some sticky and caked soil layers, especially fertilizers with high dietary fiber content, so as to create a suitable growth environment for roots.
2. The seeds planted here are varieties, and different varieties have different yields and qualities. Crops grown at home generally like to grow some old varieties. Although the yield is low, it tastes good. Large-scale planting, the important thing is the yield and quality. The same variety, some people yield tens of thousands of kilograms per mu, and some people yield several thousand kilograms per mu, but the yield is several times different. Therefore, no matter what you plant, it is particularly important to choose varieties.
3. Close planting is sparse planting. In other words, the row spacing and plant spacing of different crops are different. The plant spacing is too thin, the yield is not high, the land resources are consumed, and the plant spacing is too dense, which leads to poor sunshine and ventilation and is not conducive to the normal growth of crops.
Fertilizer is very important to decide whether crops grow well. Fertilizers can be divided into organic fertilizer, organic fertilizer and foliar fertilizer. Long-term use of organic fertilizer can turn over soil, fertilize fields and grow roots, improve soil fertility and intestinal probiotics, and reduce the occurrence of pests and diseases. It is an irreplaceable fertilizer. Organic fertilizer is beneficial to increase crop yield, and foliar fertilizer plays an auxiliary role in seedling growth. These three types of fertilizers can be flexibly matched according to the actual situation.
5. Water is the life of green plants. Without water, any green plant has no life, but water is two knives. Without water and drought, crops will stop growing, wither and wither. Too much water, lack of oxygen in the soil layer, difficulty in root respiration, root rot and seedling death. Therefore, watering is a technology, which can neither make the soil too dry nor make the soil too wet. It is best to look at the wet and dry.
6. As the saying goes, management is the most important thing in planting good crops. Daily management includes: replanting seedlings, turning over soil, weeding, cutting technology, watering, fertilizing and loosening soil. This kind of work cannot be relaxed at all.
7. Maintenance here refers to protecting crops from pests and diseases. In other words, pest control is a very important work in vegetable management methods. Procrastination and carelessness are essential. The earlier the preventive effect, the better. If the pests and diseases are serious, even the best methods and drugs will be wasted. So prevention will surpass prevention. No matter what kind of vegetable crops you plant, you should take precautions in advance. You can choose some harmless biological agents, harvest roots early and spray them early to prevent problems before they happen.
8. I don't need to talk about this. Generally, crops should be clearly planted, which is not suitable for picking immediately, but it is not suitable for picking too early.
In addition to the above eight-character mantra, we should also pay attention to the following points: ① No matter whether it is new varieties or new technologies, new methods or new skills, we must experiment before using them. (2) Watering must follow the principle of seeing dry and wet, and it can't be watered for a long time, nor can it be too dry. (3) No matter what fertilizer you use, you should keep a certain distance from the root system and don't directly contact the root system. (4) When using drugs to control diseases and insect pests or spraying foliar fertilizer, water must be prepared according to the specified proportion, and it is not allowed to be prepared at will.
