Abstract
The invention relates to an applying method of a slow/controlled release nitrogen fertilizer during cultivation of cotton bred in a feeding block. The total consumption of the slow/controlled release nitrogen fertilizer is 150-180kg per hectare of cotton in the terms of pure nitrogen, wherein 25-40 percent of the slow/controlled release nitrogen fertilizer is used for breeding the cotton in the feeding block, and the balance of the slow/controlled release nitrogen fertilizer is used for field production; a combination of a slow/controlled release nitrogen fertilizer with a controlled release period of 3 months and a slow/controlled release nitrogen fertilizer with a controlled release period of 4 months is selected for being used in breeding of the feeding block and field production respectively; and the slow/controlled release nitrogen fertilizer for breeding of the feeding block is uniformly blended in nutrient soil during breeding of the cotton, and the slow/controlled release nitrogen fertilizer for the field production is uniformly spread on the surface of soil in a field before the cotton seedlings are transplanted, and is ploughed and buried. The slow/controlled release nitrogen fertilizer is applied by using the applying method, and thus the growth and development of the root system of the cotton can be promoted, and the utilization rate of the slow/controlled release nitrogen fertilizer is increased.
Description
Technical field
The present invention relates to the application process of a kind of slow/controlled release nitrogenous fertilizer in feeding block seedlings raising cotton culture, belong to Slow/Controlled Release Fertilizers applied technical field.
Background technology
In recent years, the research and development of the production technology of China's slowly/controlled releasing fertilizer were swift and violent with industrialized development, and kind constantly increases, and production capacity improves rapidly, in agricultural production crop application more prevalent, and welcome by peasant.Slow/controlled release nitrogenous fertilizer is the main species of Slow/Controlled Release Fertilizers, accounts for the more than 90% of China's slowly/controlled releasing fertilizer total amount.
Cotton is the Main Economic crop of China, plants cotton more than 400 ten thousand hectares throughout the year, and total producing ranks first in the world.It is a ripe advanced culture technique that cotton nutrition is grown seedlings, it can effectively relax the contradiction that cotton and other crops in multiple cropping strive ground, strive season, and yield and quality, all higher than live cotton, occupies compared with critical positions in cotton culture, particularly in the area of having a large population and a few land.
At present, the application study of Slow/Controlled Release Fertilizers on cotton is mainly special fertilizer and formula thereof, effect of fertilizer, as CN101177368A (200710114007.6) discloses controlled release fertilizer special for cotton and preparation method thereof, the single-dose application before sowing cotton seed of this Controlled Release Fertilizer, no longer topdresses.CN102173961A (201010601701.2) provides a kind of disease-preventing type controlled release fertilizer special for Xinjiang cotton and preparation method thereof and application, and this disease-preventing type controlled release fertilizer special for Xinjiang cotton is disposable employed in the time of sowing cotton seed or transplanting.The Slow/Controlled Release Fertilizers application process of mentioning in above-mentioned file is very simple.In fact, fertilizing method is extremely important for the fertilizer efficiency of slow/controlled release nitrogenous fertilizer and the raising of output of cotton.Cotton belongs to circle heap root system, and lateral root is overhead starting to occur on the main root of 3～4 centimetres, and forms multilayer (row).Lateral root stretches and can exceed 70 centimetres to surrounding, most within 40 centimetres.The soil depth that cotton root system distributes is mainly at 10～30 centimetres, and along with far away apart from main root, the density of root reduces gradually.Theoretically, making all roots all absorb fertilizer nutrient is to improve utilization rate of fertilizer, increases the optimal selection of crop yield, but in practical application, is difficult to accomplish.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of slow/controlled release nitrogenous fertilizer application process on cotton, the particularly application process in feeding block seedlings raising cotton culture, to promote the applications well of slow/controlled release nitrogenous fertilizer on cotton, improve fertilizer utilization efficiency, increase output of cotton.
