Saline and alkali vegetables pay attention to
First, according to the salt content of soil, choose the land with high salt content of vegetables to plant vegetables with strong salt tolerance, such as sugar beet, spinach, pumpkin and cabbage, etc., and use low-altitude land to grow beans and leeks. Vegetables with moderate salt tolerance such as garlic, celery, and mustard are appropriate; for lands with low salt content, vegetables such as solanaceous vegetables, Chinese cabbage, and radishes can be used for salt- and alkali-tolerant vegetables.
Second, increase the application of organic fertilizer and acid fertilizer vegetable field Adding green manure, composting compost and manure and other strong saline-alkali organic fertilizer, can improve the soil structure and promote soil fertility; At the same time apply ammonium phosphate, ammonium sulfate and other acidic fertilizers to Buffer the alkaline of the soil, gradually achieve the purpose of salt alkalinity, do not use ammonium bicarbonate, ammonia and other alkaline fertilizers, so as not to increase the degree of soil salinization.
Third, the use of seedling cultivation techniques Saline and alkali vegetables, seedling protection is the key, so it must adopt seedling cultivation techniques.
1. Dishes should be made high, narrow, short, and the ditch should be deep and easy to drain.
2. The plough should not be too deep to prevent the upturn of the saline-alkaline soil under the plough layer and to follow the cultivation and planting.
3. The site preparation must be leveled to prevent back salinity at high altitude and to facilitate uniform irrigation.
4. The seeds are sowed after soaking and germinating before sowing, soaking the bottom water before sowing is conducive to emergence. After sowing, wheat straw and rice straw can be used to cover the ground to prevent returning salt.
5. Do not water before emergence, so as to avoid soil compaction, affect the emergence.
6. The amount of watering when transplanting vegetables must be more than the amount of watering when the neutral soil vegetable field is transplanted. This can achieve the purpose of flushing saline and alkali and preventing the return of salt. It is beneficial to live trees, if using furrow irrigation, irrigation To be uniform, drain the water after irrigation and wash away salt.
7. Seedlings are kept in the early morning; seedlings are preserved in the late seedlings.
8. Be sure to loosen the soil to prevent the soil from being knotted. After the rain or watering, it is necessary to loosen the soil in time to reduce the evaporation of water and salt.
