Description
Technical Field
The invention relates to the technical field of fertilizer production and processing and fertilization, in particular to a water-soluble compound fertilizer special for cotton and a preparation method thereof.
Background
"gas" is one of six major elements of soil, O in soil2When the content is more than or equal to 15 percent, the plant roots are light in color, rich in capillary roots and strong in absorption capacity; o in soil2When the content is less than or equal to 10 percent, the development of root systems is hindered, and the roots are short and dark; when the soil is O2When the content is less than or equal to 5 percent, the aerobic respiration of the root system is inhibited, and consequently, a large amount of ethanol, lactic acid and other harmful metabolites are accumulated in the root, so that the function of the root is lost, the root system stops growing and is easy to rot.
Cotton is a typical terrestrial deep root crop with O transport to the root via the stem and leaves2The cotton has limited capability, and poor ventilation of the rhizosphere environment can cause the inhibition of cotton growth, the reduction of mineral element absorption and the reduction of dry matter accumulation.
China is the second cotton producing country in the world, the cotton yield in 2020/2021 years is about 595 ten thousand tons, wherein the Xinjiang cotton yield is 520 thousand tons, and the yield accounts for about 87 percent of the domestic yield. The Xinjiang cotton planting adopts a mulching film covering and under-film drip irrigation cultivation mode in a large area, and a mulching film covered by a cotton field is tightly attached to the ground, so that gas exchange barrier in soil is caused; frequent drip irrigation under the film, soil air is discharged in the irrigation process, and soil O is caused by film covering and irrigation2Reduce the cotton shortage O2. The cotton is low in O2In sensitive crops, the influence of the ventilation condition of the rhizosphere on the root volume, the root biomass, the root-crown ratio and the mineral element absorption is large, so that the growth of cotton is influenced, and the yield is reduced. At present, intertillage and soil loosening methods are adopted in production to increase soil air permeability so as to relieve low oxygen content of plants2The stress is applied, but the intertillage and soil loosening can only be performed at the edge of the mulching film, so that the integrity of the mulching film needs to be protected to the maximum extent to ensure the heat preservation and moisture preservation effects of the mulching film, and the cotton field in the middle row of the mulching film cannot be intertillated, so that the cotton in the middle of the mulching film cannot be ventilated all the time.
Increase of O by application2Fertilizer, rich in O in soil2Can promote root respiration and microbial metabolism, and relieve cotton suffering from anaerobic infection2Coercion, enabling root Domain O2The environment is optimized, the growth of cotton can be promoted, the number of bolls, the weight of single bolls and the clothes rate of a single plant are obviously increased, and the increase of the oxygen fertilizer is favorable for improving the yield of cotton drip irrigation under the film.
