Description
Technical field
The present invention relates to farm crop prescription special fertilizer technical field, be specifically related to a kind of fused mass granulating biochemical fulvic acid fertilizer special for cotton.
Background technology
Cotton originates in tropical and subtropical region, is a kind of perennial short day crop.Through long-term artificial selection and cultivation, move northward gradually the temperate zone, develop into annual crop, can be divided into sowing time, seedling stage, flower bud phase, flowering and boll-setting period and 5 stages of the term of opening bolls.Cotton is the requisite of people's lives, also is important industrial raw material and material, plays an important role in the national economic development, and market demand is larger.
Studies show that, 100 kilograms of gined cottons of every production need 10～18.5 kilograms of absorbed nitrogens, phosphorus (P
2O
5) 3.5～6 kilograms, potassium (K
2O) 13～16.5 kilograms, the ratio of absorbed nitrogen, phosphorus, potassium three elements is roughly 3: 1: 3; 1 ton of dry-matter of the every formation of cotton needs to absorb 106 gram iron, 15 gram boron, 14 gram manganese, 16 gram zinc, 0.77 gram molybdenum.Cotton is the dark crop of root, and vegetative period is long, and fertilizer requirement is large, and seedling stage, flower bud phase, flowering and boll-setting period and each stage in the term of opening bolls need the characteristics of nutrient different, therefore how selecting properly fertilizer and the rational application of fertilizer are the keys that guarantees high cotton yield and improve cotton quality.
Be used at present all kinds of compound (mixing) fertilizer of cotton growth, have following problem:
1, mostly number average is common mineral manure, and life-time service can make soil become to harden, and soil fertility weakens, and the crumb structure of soil is destroyed serious;
2, fertilizer nutrient is inhomogeneous;
3, the utilization ratio of fertilizer is low, easily causes the fixing and loss of nutrient, not only wastes resource, and easy contaminate environment;
4, hypotrophy face does not generally contain the trace elements such as boron that output of cotton and quality are significantly increased, iron, zinc, manganese, molybdenum, causes the not high and quality of output of cotton to descend;
5, the poorly water-soluble of fertilizer is not suitable for time saving and energy saving and significantly improves the water-fertilizer integral fertilization mode of utilization rate of fertilizer.
Summary of the invention
For the deficiencies in the prior art, on the basis of high tower fused melt granulated compound fertilizer device, according to the fertilizer performance of cotton planting soil, regulation of fertilizer requirement and fertilizing method in conjunction with cotton growth, carry out scientific and reasonable prescription, and by field experiment, obtained phasic results.The object of the invention is to improve the shortcoming of prior art, and a kind of biochemical fulvic acid fertilizer special for cotton and production technology thereof are provided.

5) 14 mg/kg, available potassium (K
2O) 160mg/kg.
Cotton variety is in the new land No. 4.
Establish altogether 5 processing, the concrete processing sees Table 1, and every processing repeats 3 times, and random district group is arranged, and the experimental plot area is 30m
2, 5m * 4m rectangle establishes guard rows all around, sowing cotton 90 strains of every residential quarter.All are processed rate of fertilizer application and are 750kg/hm
2, every residential quarter rate of fertilizer application is 2.25kg, and equal 1/5 fertilizer is used for base to be executed, and 4/5 is used for imposing, and imposes a minute seedling stage, flower bud phase, flowering and boll-setting period, the term of opening bolls four times, and each, rate of fertilizer application and fertilization mode specifically saw Table 1 in period.
Table 1 Cotton fertilization is processed
Annotate: TE-trace element, BFA-xanthohumic acid
Table 2 output of cotton consists of and yield result
Annotate: in the table between the different letter representation different fertilization of same row difference reach 5% conspicuous level.
From the output of cotton constituent element of table 2, the impact heavy on bell and ginning outturn of the fertilizer of different proportionings is also little, and emphasis is the output that has influence on cotton by affecting single-strain bell-forming number.Single-strain bell-forming number, unginned cotton's output are consistent with lint yield trend, and all to process C, namely proportioning is that the water-soluble fertilizer efficiency fruit of 18-6-16+TE+BFA is best.Processing A, C, D are water-soluble fertile processing that contains trace element and xanthohumic acid, on individual plant bell number, unginned cotton's output and lint yield, all be significantly higher than the water-soluble fertile treatments B that does not contain trace element and xanthohumic acid, illustrate that the trace element and the xanthohumic acid that contain in the fertilizer special for cotton of the present invention can significantly promote nourishing and growing and reproductive growth of cotton, and then improve output of cotton.Processing A, B, C, D are water-soluble fertilizer, all are significantly higher than the common fertilizer control treatment on individual plant bell number, unginned cotton's output and lint yield, illustrate that water-soluble fertilizer is for more meeting the fertilizer of cotton growth demand.
Therefore, fertilizer special for cotton nutrient proportioning of the present invention is the most reasonable with the water-soluble fertilizer of 18-6-16+TE+BFA, is the water-soluble fertilizer of 16-6-18+TE+BFA and two proportionings of 20-8-12+TE+BFA secondly.
