Description
technical field
The present invention relates to farm crop formula 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 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, is also important industrial raw material and material, in the national economic development, plays an important role, and market demand is larger.
Research shows, 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, need to absorb 106 grams of iron, 15 grams of boron, 14 grams of manganese, 16 grams of zinc, 0.77 gram of 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 feature 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.
For all kinds of compound (mixing) fertilizer of cotton growth, there is following problem at present:
1, great majority are all 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 of nutrient and runs off, and not only wastes resource, and easy contaminate environment;
4, not comprehensive nutrition, general containing trace elements such as the boron that output of cotton and quality are significantly increased, iron, zinc, manganese, molybdenums, cause the not high and quality of output of cotton to decline;
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 formula, 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.

Cotton variety is in new land No. 4.
Establish altogether 5 processing, specifically process in Table 1, every processing repeats 3 times, and random district group is arranged, and experimental plot area is 30m
2, 5m * 4m rectangle, surrounding is established protection row, sowing cotton 90 strains of every community.All processing rates of fertilizer application are 750kg/hm
2, every community rate of fertilizer application is 2.25kg, and equal 1/5 fertilizer is executed for base, and 4/5 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 were specifically in Table 1 in period.
Table 1 Cotton fertilization is processed
Note: TE-trace element, BFA-xanthohumic acid
table 2 output of cotton forms and yield result
Note: in table, between the different letter representation different fertilization of same row, difference reaches 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 by affecting single-strain bell-forming number, to have influence on the output of cotton.Single-strain bell-forming number, unginned cotton's output are consistent with lint yield trend, and all to process C, the water-soluble fertilizer efficiency fruit that proportioning is 18-6-16+TE+BFA is best.Process A, C, D for containing water-soluble fertile processing of trace element and xanthohumic acid, on individual plant bell number, unginned cotton's output and lint yield, be all 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 in fertilizer special for cotton of the present invention, contain 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, on individual plant bell number, unginned cotton's output and lint yield, are all significantly higher than common fertilizer control treatment, 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 secondly the water-soluble fertilizer of 16-6-18+TE+BFA and two proportionings of 20-8-12+TE+BFA.
