Recently, many growers have asked “how to improve the soilâ€. This problem seems simple. In fact, it is difficult to improve. Because about 70% of growers use chemical fertilizers to maintain crop growth throughout the year, short-term crops are growing well, but in the long run, they will only lead to soil translocation. In fact, many times the problems of seedlings are not long or the yellowing is serious, and the root system is related to soil problems. Below, Huinong.com will tell you about the soil improvement methods that the college teachers have shared.
1. Insufficient organic matter in the soil
It is still very difficult to grow enough organic fertilizer sources on a large scale. Therefore, planting grass as a source of organic matter is carried out at the same time as opening, but poor soil grass is not easy to grow. The most deficient in reclamation is nitrogen, so it is necessary to apply sufficient nitrogen fertilizer to plant grass. Apply 20 kg per 1,000 square tons of urea, then cultivate, and then plant the grass seeds in a few days. In short, use cheap organic matter and nitrogen fertilizer.
Second, the use of rice husk as a modified layer of soil
The water permeability of the soil layer is poor because the particles of the soil are small. So it is better to mix it with thick sand and soil. Loose coarse sand is a good mix of soil and soil, which requires considerable cost, but the effect is permanent and cost-effective in the long run.
However, most of our growers have large investments in the early stage. Students with capital can adopt the above methods. Here we introduce a low-cost, money-saving method to improve the minimum cost of soil. There is no threshold, and every grower can try.
Use rice husk husks to scatter the ground before the trenching. Then use a trencher to dig trenches. The amount of rice hulls is appropriately added according to the nature of the soil. Generally, a bag of rice husks of about 15 kg can be mixed in soils of 50 cm in width, 50 cm in depth and 1 m in length.
In the actual operation process, the effect of deep ploughing at the same time will be better. A cubic meter of soil is added to the rice husk and pig manure composting 200 kg, or 60 kg of rice husk is applied and then deep-plowed. It must be noted that it is necessary to connect the ditch. Otherwise, there will be water in the deep ploughing place, which may be counterproductive.
The above is the soil improvement method compiled by Huinong. I introduced it to the rice husk in the above. In fact, the crude organic matter can be used, such as broken straw, mushroom residue, sawdust, etc. It is worth mentioning that It is not necessary to bury these in the soil. Be careful to mix and make the soil loose and breathable.
