Cotton seedlings are ready to prepare for fertilizer

The preparations for cotton nutrition and nursery are still relatively slow. From the mentality of cotton farmers, the first is how much cotton has been decided this year, and it has not yet been determined how many seedbeds are arranged. Second, it has not paid enough attention to improving the quality of seedbeds. Third, it is considered that there is still time for sowing seedlings. Therefore, some farmers have not reserved cotton seedbeds, and some have not kept the seedbeds. Some farmers are also preparing to prepare land, while preparing soil, fertilizing, and sowing. This status quo shows that the basic work of this year's cotton nutrition and nursery is still relatively weak. In order to improve the quality of cotton nutrition and cotton seedlings, seedbeds must be prepared with high standards and high quality.

First of all, to stay in the seedbed area. How much is the area of ​​the seedbed, one depends on the planned area of ​​cotton planting, the second depends on the density of the cotton field, and the third depends on the size of the nutrient diameter. There are three types of nutrients in the region: large, medium and small. The diameter of the big toad is 7 to 8 cm, the diameter of the middle is 5 to 6 cm, and the diameter of the small toad is 4 to 5 cm. There are about 250 square meters per square meter, about 400 square meters per square meter, and about 600 small square meters per square meter. At present, most of the cotton varieties are mainly transgenic hybrid insect-resistant cotton, with a density of 1,500 per acre, and 20% to 30% of the prepared cotton seedlings are removed. The seedling bed is about 8 square meters per acre. A seedbed of 6 square meters is required for each acre, and a seedbed of 4 square meters per acre is required.

Second, we must thoroughly deepen the bed soil. The address of the seedbed should be chosen to avoid the wind and the sun, the energy can be filled, and the transportation is convenient. The seedbed should be replaced every year, and the old seedbed should not be used to reduce the invasion of germs. The bed soil should be deepened by 20~30 cm to facilitate full ripening, and the weeds, eggs and cockroaches should be turned out to expose them to frostbite. Before sowing, the seedbed should be finely tidyed twice, so that it can be squeezed into a group, the ground will be scattered, and the soil will be cleaned.

Third, we must rationally formulate fertilizer. Nutritional seedling bed, as the name suggests, is to be rich in nutrients, scientific formula, timely fertilizer, and bred early and young. According to local experience, generally 10 to 15 tons of decomposed clean water manure, 25 kg of phosphate fertilizer, 10 kg of potassium fertilizer, or about 25 kg of high-content compound fertilizer is applied as a base fertilizer per mu of seedbed. To seize the sensation, while fertilizing, the whole seedling bed, so that it is evenly mixed, improve the performance of fertilizer and water retention. Do not use urea as a base fertilizer before sowing, in case the biuret causes the dead seedlings.

Fourth, the disaster response is prepared for the bauxite. If the best planting season has arrived, it is difficult to plant the seeds in continuous rainy weather, which will delay the farm time. In this regard, the way to adapt is to catch the fine weather, first use the old plastic film to cover the prepared nutritious soil to prevent the rain from getting wet, and the rain can be done on time. It is necessary to open the ditch around the seedbed to filter the water, so that the deep ditch can lift the bed, and the rain can live, and fight for time and early breeding.
