Description
Technical field
The present invention relates to Crop fertilizer, specifically, relate to a kind of special base fertilising of cotton being suitable for Huanghai Sea Plain and preparation method thereof and application.
Background technology
Huanghai Sea Plain comprises to the west of Beijing and Tianjin suburbs and counties under the jurisdiction of a large city, large portion, Hebei, Yellow River in Shandong Province and Yellow River in Henan northern area, and belong to the moistening or subhumid climate in warm temperate zone, cotton is one of the major economic crops in this Plain, accounts for more than 20% of the national cotton field total area.Improve cotton per unit area yield and plant the key issue of cotton benefit Shi Gai district Cotton Production sustainable development, and common saying says " crops YIZHIHUA. complete in fertile manager ", economic and reasonable fertilization is a wherein important technique measure.
The required nutritive element of Developmental of Cotton has 16 kinds: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, boron, copper, zinc, molybdenum and chlorine, carbon is from carbonic acid gas, hydrogen is from water and air, oxygen is from carbonic acid gas and air, other 13 kinds of nutritive elements, mainly from soil, are called mineral nutrient element.Nitrogen, phosphorus and potassium are the more 3 kinds of nutritive elements of cotton requirement, being thus called as " plant nutrition three elements " or " major fertilizer elements ", usually need carrying out the deficiency of supplementary soil content by using these three kinds of fertilizer; Huanghai Sea Plain part Cotton Soil boron, Zn content is also not enough, also needs to use boron, zinc fertilizer; Other mineral nutrient element, the contents level of Huanghai Sea Plain Cotton Soil generally can be satisfied the demand, and lessly uses.
Cotton is taproot system deep rooted plant, and breeding time is long, and fertilizer requirement is large, and seedling stage, flower bud phase, flowering and boll-setting period and nutrient demand feature of each stage in the term of opening bolls are different.According to the study, Huanghai Sea Plain often produces 100kg gined cotton, average absorption N, P
2o
5, K
2o is respectively 13.1kg, 4.6kg, 10.3kg, and the ratio of three is 1: 0.36: 0.80; Cotton is the crop responsive to boron, zinc reaction, and during serious boron deficiency, flower bud comes off seriously, appearance " flower bud and do not spend "; During serious scarce zinc, flower bud and children easily come off age.
The subject matter that current Huanghai Sea Plain Cotton fertilization exists is that nitrogen, Phosphorus fertilizer usage are obviously bigger than normal, and potash fertilizer and micronutrient boron, zinc Term Fertilization is not enough, causes cotton field nutrient imbalance, namely Cotton Soil nitrogen, phosphorus residual quantity are high, potassium deficiency, boron, zinc area constantly expand, and deficiency extent is deepened year by year.The principle that the fertilising of cotton field, current Huanghai Sea Plain should be followed " control nitrogen, subtract phosphorus, increase potassium, mend boron zinc ".Research for many years shows, Huanghai Sea Plain lint yield 80 ~ 100kg/ mu, N, P
2o
5, K
2about O Optimum is respectively 12 ~ 15kg/ mu, 6kg/ mu and 8 ~ 10kg/ mu, wherein nitrogenous fertilizer base executes 40% ~ 50%, and the whole base of phosphate fertilizer is executed, and the whole base of potash fertilizer is executed or base is executed 60%, imposed 40%.Wherein base manure is used is the key of the cotton rational application of fertilizer, and its core technology is the proportioning of nutrient in fertilizer.
The common Chemical Mixed Fertilizer sold in the market and the general the content of nitrogen and phosphorous of fertilizer special for cotton higher, and potassium content is on the low side, majority is boracic, zinc nutrient not, be not inconsistent with the nutrient uptake feature of cotton and Huanghai Sea Plain Cotton Soil nutrient situation, use rear easily cause nitrogen, phosphorus nutrient waste and cotton there is potassium deficiency and boron, zinc symptom, do not reach optimal production.Patent announcement number is that the Chinese patent of CN102643125B discloses a kind of fertilizer special for cotton, mixed by proportioning by the chicken manure become thoroughly decomposed, ammonium chloride, diammonium phosphate, Repone K, borax, ammonium molybdate six kinds of raw materials, be intended to activating soil, improve " hard bell " symptom in continuous cropping drawback and field, its application is confined to Soil Development in Huaibei Plain Soils In The Region feature, and time of application and method not specified (NS), N:K is proposed simultaneously
2o element ratio is 1:1 ~ 2, and this does not obviously meet Huanghai Sea cotton region cotton nutrient demand and Soil Nutrient Status.Patent announcement number is that the Chinese patent of CN103073365B discloses a kind of fused mass granulating biochemical fulvic acid fertilizer special for cotton and production method thereof, close zinc 1-15 part, EDTA Chelated Manganese 1-15 part, EDTA chelated iron 1-20 part, borax 1-20 part, Ammonium Heptamolybdate 0.1-0.5 part for raw material with ammonium nitrate phosphorus 450-650 part, Repone K 50-160 part, potassium sulfate 80-300 part, monoammonium phosphate 50-150 part, biochemical fulvic acid 1-100 part, EDTA huge legendary turtle, obtain special fertilizer through mix and blend, heating, granulation, cooling, screening.This fertilizer has the features such as good water solubility, green, improvement soil.But cost is high, fertilizing method is complicated, and it is 1/5 that proposition base is executed, and imposing is 4/5, is not obviously also suitable for Huanghai Sea Plain cotton uptake characters, also uneconomical.Patent announcement number is that the Chinese patent of CN102491815B discloses high-concentration nano-carbon cotton special fertilizer and preparation method thereof, by urea, potassium primary phosphate, Repone K, fused(calcium magnesium)phosphate, monoammonium phosphate, ferrous sulfate, zinc sulfate, EDTA huge legendary turtle closes manganese, borax, ammonium molybdate, nano-sized carbon is by regulation proportion ingredient, nitrogen, phosphorus, the ratio of potassium three elements is roughly 3:1:3, its object increases potassium and increases calcium, and Huanghai Sea Plain belongs to northern Fu Gai district, the confession calcium ability of soil is strong, in addition, fertilizing method belong to base manure and topdress, do not form formula and fertilizer practice for the base fertilising being exclusively used in cotton.Other patent applications are as CN1554623A (fertilizer special for cotton), CN1078454A (preparation method of fertilizer special for cotton), CN1101638A (fertilizer special for cotton and preparation method thereof), a kind of fertilizer special for cotton such as CN1519271A, CN102329172A, CN102491831A and CN102206125A etc. all propose composition and the proportioning of the certain limit of fertilizer special for cotton, but it is not enough to there are some inventions, or its application process is not described, or be not exclusively suitable for making cotton field base manure etc., or preparation method is unclear.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide one special base fertilising of cotton being suitable for Huanghai Sea Plain (comprising Beijing, the large portion of Tianjin suburbs and counties under the jurisdiction of a large city and Hebei province, the area to the west of Yellow River in Shandong Province and to the north of Yellow River in Henan) and preparation method thereof and application.
