2 King East sugarcane field soil fertility reasons
2.1 Sandstone dam along the Chuanhe River
The rainy season of sand dams along the Chuanhe River is often affected by floods, river diversions and surface runoff cuts, resulting in a decline in land fertility. The partial diversion of the Chuanhe River will also make it impossible to fix the land for a long period of time. The newly-deposited place will have a thin soil and a relatively sandy texture, and the surface will have pebbles of different sizes, resulting in low fertility.
2.2 Paddy Fields as Cane Fields
Chuanhe Pingba and Ganhe River cane crop rotation area is a local production area of ​​a variety of economic crops, sugarcane, sericulture, grain, flue-cured tobacco and other conflicts are prominent, continuous cropping phenomenon is widespread. Farmers tend to focus on applying inorganic fertilizer rather than on farmer's fertilizer, resulting in soil compaction, poor permeability, imbalance of nitrogen, phosphorus, and potassium, and ultimately lead to decreased soil fertility.
2.3 Dam margin and degraded hill sugarcane field
Most of these sugarcane field soils are odoriferous soils. In addition, there are many sloping farmland, and the length of cultivation is short, the degree of soil maturity is low, and soil erosion is serious. However, the application of organic fertilizer and phosphorus and potassium fertilizers after planting and transplanting were not carried out in a reasonable intercropping or rotational soil for fertilization, which also contributed to the decline in soil fertility.
Method and Measure of Soil Improvement in Jingdong Sugarcane Field
3.1 Accelerating the sugarcane field infrastructure
In the sugarcane areas along the banks of the Chuanhe River and the Jianhe River, we must strengthen the basic construction of farmland, take the improvement of soil and water as the center, plan the fields, canals, and roads in a unified way, level the land, deepen the soil, cultivate the mature soil, and achieve energy discharge. Irrigation, improve soil fertility. Barren slopes with slopes exceeding 25°. It is necessary to vigorously plant trees and afforestation, maintain water and soil, prevent wind and sand, and promote the restoration of soil fertility, so as to achieve the purpose of water conservation, fertilizer conservation, and soil conservation, so that sustainable use can be achieved.
3.2 Carry out reasonable rotation and interplanting
The establishment of a reasonable sugarcane rotation and intercropping system is conducive to the formation of a benign circulatory system for sugarcane production, which can improve soil physicochemical properties, improve soil fertility, reduce wind, drought, flooding, diseases, insects, grasses, etc., and cause premature maturation. To achieve early maturation, high yield, and high sugar.
3.2.1 Rational rotation
Reasonable crop rotation includes crop rotation, legume crops, green manure and sugarcane rotation. The paddy field sugarcane rotation includes: planting sugarcane, sugarcane, sugarcane, rice and wheat; planting sugarcane, sugarcane, sugarcane, rice-canola, planting sugarcane, sugarcane, sugarcane, rice, soyabean, planting sugarcane, sugarcane, and sugarcane. vegetables. Rotation of rice and sugarcane, alternating between wet and dry, can enhance soil aeration performance, make full use of nutrients from different soil layers, renew soil nutrients, and eliminate toxic substances in the soil. The rotation of leguminous crops and sugarcane can regulate soil nutrients and prevent excessive consumption of soil nutrients.
3.2.2 Interplanting Science
Growing crops such as grain, melon beans, and vegetables in the sugar cane line. Different growth stages and high and low plants are matched to each other to form different levels of spatial structure, and the sun's fertility is fully utilized. The legume symbiotic rhizobia can also fix nitrogen and increase soil nitrogen nutrition. Crop stalks and residues can also increase soil. Organic matter is good for fertilizing soil.
At present, the inter-planting model for sugarcane fields promoted by the local people mainly includes the following three types: First, a winter and spring sugarcane planting pattern for vegetables. The interplanted vegetables were planted in early January. The rows of vegetables, cabbage, and cabbage were 20cm×20cm, 25cm×23cm, and 30cm×30cm respectively. The sugarcane was planted in late February, and the row spacing was 100-110cm and 60-80cm (wide and narrow rows). There are 120,000 buds under the hectare. The second is a spring sugar cane planting mode. Cucumber, U.S. primum squash (Sycamore melon) sown in early January, 50 to 60 cm from the cucumber and 80 to 90 cm from the zucchini, and from the end of February to the beginning of March in the sugarcane, 90 to 110 cm and 60 to 70 cm wide and narrow rows. Guaranteed 150,000 buds per hectare. The third is the spring model of sugar cane planting. Sugarcane row spacing 110cm and 70cm (wide and narrow row), interplanting early-maturing hybrid corn, sugarcane from the end of February to the beginning of March, to ensure 150,000 buds per hectare, timely sowing of corn in late March, pond distance 50-60cm, sowing 2 per pond .
