In recent years, in order to stabilize the area of ​​cultivated land, ensure food security, improve resettlement, and stimulate economic growth, the country has successively initiated land management projects based on the reform of low hills in many areas. From the perspective of the land management that has been completed so far, although the slope of the new cultivated land has slowed down and the land mass has become larger, the original cultivation layer has been disrupted, and the “rehabilitation area†has become a “living place†with more roots and weeds. Poor soil structure, low fertility, low organic matter content, poor farmability and other issues are more prominent, affecting the enthusiasm of farmers. Increasing the follow-up fertility of newly-controlled farmland and rapidly “ripening†it into high-yielding fields has aroused great attention from all localities. For the new cultivated land, the following follow-up fertilizer measures can be taken:
1, do a good job of chemical weeding. In order to remove the stones, roots, and grass roots as far as possible, the new management of arable land should be performed on chemical weeds if weeds are serious. The new cultivated land is mainly perennial perennial weeds such as Imperata cylindrica, Phragmites australis, and Cyperus rotundus. The number of other weeds is also high, and common herbicides have poor control effects. According to my county's test, before the crop is cultivated, weeding herbicides that use phytotoxic, herbicidal herbicides capable of killing weeds and roots without residue remain the best herbicides. The specific method of use is after the emergence of weeds, with 41% of the "first-hand" water agent 400 ml, watered 30 kg, evenly sprayed on the weed stems and leaves. Weeds generally start to yellow after 3-5 days and begin to die within 7-10 days. In addition, we can also use other herbicides such as Roundup and Thai Fire.
2, increase organic fertilizer. The new management of cultivated land has poor basic fertility and low fertility levels. It is necessary to try to broaden the sources of fertilizers and increase organic fertilizers. It is best to add 4,000 kilograms of livestock and poultry manure per acre. Apply shallow plough after application and turn fertilizer into soil. In remote plots where farmyard manure and livestock manure are not easily transported, it is advisable to increase 200 kg per acre with a high-efficiency bioorganic fertilizer made from dried poultry manure combined with chemical fertilizers to improve soil physical and chemical properties and increase soil activity. The use of organic fertilizers combined with the use of biological nitrogen-fixing or bio-potassium fertilizers is more effective.
3. Use soil rapid curing agent. For newly treated farmland with a large proportion of raw soil, soil rapid curing agents can be applied. According to the test, the product has a significant role in promoting the formation of soil aggregate structure, increasing soil organic matter content, and enhancing soil enzyme activity. The application of the product can increase the crop yield by 15-20%, and the soil ripening time can be shortened from 7-8 years to 2- 3 years.
4. Pre-planting of cultivated land crops. For the new cultivated land, especially the plots where the farmyard fertilizers are not easily delivered, green manure or other legume crops should be cultivated. For example, broad beans, peas, and milk vetch are planted in autumn and winter, and soybeans, adzuki beans, mung beans are planted in spring and summer, When planting, it is necessary to apply nitrogenous fertilizer and increase phosphorus fertilizer to promote crop growth and increase nitrogen by phosphorus. Fertilizer field can also be sown in the fall and turned over in spring. It is also possible to interplant crops or crop rotations between legume crops and other crops, and to increase income while raising crops.
5, soil testing formula fertilization. Before the new cultivated land is cultivated, sampling and soil analysis shall be conducted. According to the soil fertility and crop growth demands, the type, quantity, and fertilization method of fertilization shall be determined, and fertilization shall be strictly performed in accordance with the formula, and the soil fertility shall be continuously increased to increase the crop yield.
6, insist on returning straw. After the crops cultivated by the new cultivated land are harvested, the straws should not be burned and should be crushed and combined with deep-turning to turn them over to the field, and nitrogen fertilizer should be added appropriately. Straw can also not be crushed. When the next season crop is planted, it will cover the ground. After it is rotted, it will turn over and return to the field. After many years of continuous straw returning, it will increase soil organic matter content and gradually increase soil fertility. (Xiong Fei, Senior Agronomist, Zhushan Agricultural Bureau)
