Cotton grass covered with fertilizer to prevent fall
In recent years, in order to improve the ecological environment of cotton growth, the author has experimented and popularized the technique of stamping grass in cotton fields for many years in cotton field Daejeon. According to practice, this technique has very good ecological and economic benefits for cotton production. One is security. Before the cotton line was sealed, the blank line was exposed for more than two months. Due to the large amount of evaporation, the cotton was vulnerable to drought. After covering the grass with cotton, the water content of the soil increased significantly. It was determined that the cover grass was lower than The moisture content of the cover grass is 5%-12% higher. The second is to keep fertilizer. After a heavy rainstorm, exposed soil, nutrients can easily be lost. Gadding in the cotton field can prevent nutrient waste. According to the determination of the soil department, the grass field of the cover grass is 2.1% to 16.8% higher than that of uncovered grass. The third is to prevent the consolidation. No matter what kind of grass covers the cotton fields, the soil can be seen loose after the heavy rain has washed away and the covered grass is uncovered. The fourth is to control weeds. The rapid growth of cotton in May-June is also a period of symbiosis with weeds. After weeding in the cotton field, the weed initiation environment deteriorated and the growth of weeds was inhibited. According to the survey, the grass cover of the grass is 121.5-201.6 fewer than the uncovered grass. The fifth is to prevent lodging. For cotton transplanted with a nursery for seedlings, the main root was cut off, and cotton with more peaches and higher boll weights in the middle and later stages suffered a heavy storm, the lodging rate of the cotton plants was high, and the lodging of the cotton plants was significantly reduced and the degree of lodging was reduced. Light, easy to straighten. The sixth is to adjust the soil temperature. During the high temperature season, the temperature of 5 cm deep in the Gabka cotton field is 1.3°C-3.8°C lower than that of uncovered grass. Seven is to improve the soil. The grass covered cotton field is better than the uncovered cotton field soil pellet structure. According to the determination, the content of organic matter increased by 0.03%-0.30%. Eight is to reduce the shedding of bells. The survey found that the shedding rate of cotton budding bushes that had been covered with grass was 8.2% to 17.4% lower than that of uncovered cotton buds. Nine is cost savings. Grass and grass fields can be rotted in the cotton line that year. Compared with uncovered cotton fields, the fertilizer investment per mu can save about 30 yuan. Ten is early maturation. Grass covered cotton is more concentrated than uncovered cotton, bolling early, and being listed sooner. The average yield of lint per acre is 5%-7%. In order to better play the effect of cotton grass covering, in the specific operation should pay attention to the following matters: First, cover grass time. Cotton base fertilizer is applied more than enough, cotton buds grow more prosperous, after cultivating stubble or earthing can cover grass. If you do not apply basic fertilizer, apply sufficient fertilizer (Bully fertilizer) to cultivate the soil and then cover the grass. The time is appropriate from early June to early July. The second is cover grass species. There are many kinds of grasses that can be selected for cotton grass cover, such as straw, wheat straw, rapeseed, corn, bean stalks, glume and aquatic grass. The third is the number of grass cover. After repeated comparisons in practice, it is advisable to cover 200-250 kilograms of hay per hectare of cotton fields. Covering fresh grasses can increase the amount of grass properly. The thickness of cover grass is 5-8 cm. After the cotton is sealed, it undergoes several rainfalls. Can rot. The fourth is the cover method. After the soil is cultivated on the cotton, the grass is laid directly on the cotton line, and the grass should be evenly covered. For ridge cultivation, ridgeback furrows should be covered with grass.
