Description

Fertilizer special for cotton

Technical field

The present invention relates to agriculture production Chemical Mixed Fertilizer, particularly a kind of fertilizer special for cotton.

Background technology

Cotton is as one of Main Economic crop, very wide at China's planting range, and the production of cotton and people's daily life are closely bound up.Therefore, improve output of cotton, improve cotton quality, development China light and textile industries are significant with uplifting the people's living standard.

The height of output of cotton, the quality of quality, have close relationship with the composite factor such as cotton variety, soil, weather, moisture, fertilising, the prevention and control of plant diseases, pest control, and in factors, fertilising plays a very important role the impact of output of cotton and quality.This is that applying fertilizer is an important technique measure that increases substantially output of cotton level and improve cotton quality because fertilizer is Yield Increase In Cotton and the basic substance that improves quality.By the rational application of fertilizer, can coordinate the demand of cotton to nutritive element and the contradiction of fertilizer provision from soil on the one hand, thereby reach the object of high yield and high quality; On the other hand, available less fertilizers input, obtains higher output and maximum economic benefit, realizes cost efficiency, the object of soil protection environment.Cotton fertilization must reasonably be used according to fertility characteristic, nutritional characteristic and the regulation of fertilizer requirement etc. of cotton.

Cotton is to need fertile more crop, and the output of cotton unit surface is along with the suitable collocation of the nutritive elements such as the reasonable increase of fertilizer amount and nitrogen, phosphorus, potassium and boron, molybdenum is risen.According to the experimental study of relevant scientific research department, 10 kilograms of gined cottons of general every production, need 0.91-1.17 kilogram of absorbed nitrogen (N), phosphorus (P ₂o ₅) 0.32-0.40 kilogram, potassium (K ₂o) 0.74-1.02 kilogram, N: P ₂o ₅: K ₂o is 1: 0.35: 0.85, and absorbs appropriate boron, molybdenum element.

Nitrogen is cotton constitutive protein matter and metabolic necessary material, and the formation and development of cotton each several part organ, all needs a large amount of nitrogens.Cotton the in the situation that of nitrogen stress, poor growth, plant is short and small, blade yellow, fruit branch number and fruit joint number few, come off many.During serious nitrogen stress, the bottom Lao Ye browning that turn to be yellow, finally dries up and comes off so that become peach number few, and single bell is heavily low, yields poorly.

Phosphorus is cotton cells core and plasmic moiety, is the indispensable nutriment of synthetic protein, and phosphorus can increase viscosity and the elasticity of cellular plasm, promotes that cotton root system reaches full growth, and strengthens the drought-resistant ability of cotton, cotton seedling is looked squat real healthy and strong.When phosphorus element is under-supply, growth rate of cotton plant is slow, and root growth is bad, and leaf look dark green, and cotton plant is short and small, and reproductive growth is obstructed, knot bell and ripe postponement, and the light seed of bell is little, and mote increases, and fiber maturity is poor, and yield and quality declines.

Potassium is the indispensable nutritive element of cotton growth, and potassium, to strengthening photosynthesis, increases enchylema concentration, and improving drought resistance has good effect.When Potassium status is not enough, cotton is in seedling stage or flower bud phase, and first mesophyll chlorosis appears in stem middle part blade, and then transfers yellow to, and later blade tip and edge are dried-up, curling downwards, and last whole blade becomes reddish-brown; When serious, blade is withered comes off, and is conventionally referred to as " red leaf blight ".All this sick cotton fields, the existing cotton plant early ageing of multilist, cotton boll slight of stature, blow-of-cottons are not smooth, and fiber maturity is poor, and the output of cotton is also lower.

Boron can promote the running of cotton crop endotrophic material, participates in the formation of cell walls, accelerates merismatic growth, affects chlorophyllous structure.During boron undersupply, petiole produces endless belt, and cotton plant terminal bud is usually downright bad, long short and small of cotton plant and branch is many, and when serious, cotton plant occurs not blooming, do not tie bell, or flower bud and not flower, colored and unreal phenomenon, Severe Reduction.

Molybdenum can strengthen nitrogen metabolism, improves the activity of biological nitrogen fixation bacterium, promotes nitrogen fixation, promotes chlorophyllous formation, accelerates ascorbic synthesizing, and improves tenuigenin concentration, strengthens drought-resistant ability.When molybdenum element is under-supply, start chlorosis between vein, develop between arteries and veins and thicken subsequently, blade surface is cunning, and blade is cup-shaped, the necrotic spot of final edge generation canescence or grey, cotton boll is undesired, is similar to " the hard bell " in field, has a strong impact on output of cotton and quality.

According to relevant department's investigation statistics, current very unreasonable in Soil Development in Huaibei Plain cotton crop Fertilization Structure, show almost serious superfluous, plain quantity not sufficient, the potassium element consumption heavy losses used of phosphorus of blank, Nitrogen Amount of Rate of Organic Fertilizer, nitrogen, phosphorus, potassium three essential fertilizer ratio average out to 1: 0.22: 0.35, and have equivalent area boron deficiency, lack molybdenum.Therefore, applying organic manure on cotton crop, reduce nitrogenous fertilizer, improve phosphorus, potash fertilizer, mend with boron, molydbenum fertilizer, being the task of top priority of Cotton Production, is to increase output of cotton, improve cotton quality, reduce agricultural cost, improve the Important Action of edatope, and spread fertilizer special for cotton has important realism.

Summary of the invention
