CN103664309A - Formula of special compound fertilizer for ryegrass - Google Patents

Abstract

The invention relates to a formula of a special compound fertilizer for ryegrass. The formula is researched and developed according to the biological characteristics and growth characteristics in northern area, aiming at solving the problems that ryegrass is hard to grow in poor soil and the seedlings easily die in the northern area. The formula is characterized in that a chemical fertilizer accounts for a large proportion in the formula; the formula mainly comprises urea, diammonium phosphate, potassium sulphate, and ammonium ferrous sulfate. The formula has the advantages that all components are easily dissolved in water and can supplement the nutrient for ryegrass after being applied to the land, and thus the ryegrass can quickly grow; 30 to 55g special compound fertilizer is applied per square meter for one to three times each year; all raw materials in the formula are common materials and easily purchased; the effect is obvious after application.

Description

A kind of formula of rye grass compound fertilizer special

Technical field

The invention belongs to the field of lawn fertilizer, relate in particular to a kind of field of rye grass compound fertilizer special.

Background technology

Rye grass has another name called Britain rye grass, perennial root rye grass, it is one of turfgrass of the extensive plantation of current northern area, lolium is in cold season grass, conventionally and Festuca Arundinacea mixed seeding to reach the effect on fast rapid-result level ground, rye grass often grows thickly, well developed root system, and fibrous root is mainly distributed in 15 centimetres of topsoil, tiller numerous, in individual plant cultivation situation, can reach 250-300 or more.Stalk is upright, high 80-100 centimetre.Leaf is long and narrow, long 5-12 centimetre, and wide 2-4 millimeter, deep green, folding during children; Seed is flat, smaller.The long 4-7 millimeter of lemma, back of the body circle, has 5 of veins, matter is thin, hold blunt, without awns or approximate without awns; Glumelle and lemma are isometric, and top is sharp-pointed, and quality is transparent, the vein edge that keeps to the side, and there is fine, soft fur on limit.

The warm cool moist climate of rye grass happiness, is suitable for nice and cool, not too cold district growth in winter in summer.Can better grow in 10 ℃ of left and right, 27 ℃ following is growth optimal temperature, 35 ℃ of poor growths.The rye grass thermotolerance inequality that resists cold, not resistance to the moon.

Soil As Influenced By Ryegrass Plants requires stricter, and happiness fertilizer is not resistance to lean.Slightly can be acidproof, suitable soil pH is 6-7.The first two years that the rye grass of viewing and admiring as view completes in construction is due to meticulous foster pipe, growing way there will not be problem conventionally, growth along with rye grass, nutrient in soil is constantly absorbed and exhausts, it is more and more barren that soil becomes, the growth of rye grass is also suppressed gradually, blade starts yellow, withered, come off, even sheet is die, this is mainly because the nutrient in soil can not meet the growth demand of rye grass, in order to guarantee the sustainability on lawn, can maintain ornamental value for many years, we regularly apply fertilizer must to every year rye grass, to guarantee its normal growth.Everybody has had realized that to the importance of turfgrass fertilising at present, on market, also there is a large amount of lawn grass fertilizers, but the dedicated fertilizer for rye grass does not also have, we have carried out careful research to rye grass and have found out the dedicated fertilizer for rye grass in view of the situation.

Summary of the invention

The present invention relates to a kind of formula of rye grass compound fertilizer special, in formula, major part is chemical fertilizer, and main component is urea, diammonium phosphate, potassium sulfate and ferrous ammonium sulphate; Wherein the ratio of each composition (weight ratio) is urea 25-55%, diammonium phosphate 20-45%, potassium sulfate 5-25%, ferrous ammonium sulphate 1-12%, and each material proportionally mixes, and stirrer is puddled evenly, amount of application be (30g-55g)/square metre.Annual use 1-3 time.

Embodiment

The rye grass compound fertilizer special of preparation 50kg, from means of agricultural production shop, buy urea 45kg, diammonium phosphate 35kg, potassium sulfate 16kg, ferrous ammonium sulphate 4kg is bought in chemical industry supermarket, is placed in mixer drum, puddles evenly, spring apply sowing 3 years take rye grass in main lawn, 40 grams/m of usage quantitys, execute once autumn again, and the rye grass of applying fertilizer while entering the winter is obviously good than unmanured rye grass growing way, leaf look blackish green, without dead seedling.
