New sugarcane is the basis of ratoon cane, and the cultivation of new sugarcane is directly related to the key to the high yield and stable yield of ratoon cane. The traditional farming method in the Cane District of the town is that the no-till plough is artificially opened to shallow ditch. Generally, the depth is only about 20cm. Due to the shallow planting ditch, the new planting sugarcane is in a higher position, and the range of water absorption of the root is shallow, not only the sugar cane in the season. With low yields, the ratoon cane meal of the 2 to 3 years after the harvesting of the pre-planting cane was quickly raised to the surface of the tillage layer, and the ratooning cane production dropped rapidly.
From December to January, the soil moisture content was higher than that from February to March, but the average temperature was only 12.2e, which was lower than the minimum temperature requirement for sprouting. Low temperature was the primary factor restricting sprouting of the sugarcane sprouts, and the use of plastic film to cover the effect of moisturizing and warming In the new sugarcane planting, the ratoon cane was mulched before the sugarcane was harvested and covered with plastic film. The soil moisture and temperature conditions that affected the sprouting of the sugarcane sprouts were significantly improved. According to our analysis, the soil moisture content was 28.10% before the cover film, and the soil moisture content was kept at 25.75% 10 days after the film was covered. The water content of the film was not decreased to 12.35%, and the soil temperature was increased by 2~5e. Through the role of mulch film covering moisturizing and warming, the planting period of new planting sugarcane can be advanced to December to January. At the same time, the sugar plant can open and harvest the next season's next season's sugarcane planting sugarcane planting cane, which can make full use of the advantages of soil moisture in winter. Fast hair.
Through the application and analysis of the real-time monitoring system of soil moisture, the comprehensive technology of sugarcane three-high cultivation in dryland is a systematic project formed by applying the comprehensive complementary effects of individual technical measures. The use of improved seeds, seeding under deep-groove soil, and prevention of diseases, weeds and weeds are the basic measures for high-yielding cultivation; the ratoon cane toe planting sugarcane in the early stage of planting of new sugarcane and ratooning before ratoon cane can only be effectively increased through the use of mulching. Effective stalks prolong the advantage of single-stem growth, and appropriate close planting and N, P and K fertilizers are suitable for high-yielding cultivation objectives. Through the computer simulation, an optimized promotion program is established to ensure efficient cultivation. Therefore, as a system engineering application, various technologies must be implemented in order to achieve the goal of high yield and efficient cultivation.
