Abstract
The invention discloses a method for fertilizing orchardgrass. The method utilizes urea as nitrogenous fertilizer, calcium superphosphate as phosphate fertilizer and potassium sulfate as potassic fertilizer, wherein a weight part ratio of N to P2O5 to K2O is 1.986: 1: 2.114. The method comprises the following steps of applying all the phosphate fertilizer, 45% of the potassic fertilizer and 45% of the nitrogenous fertilizer as base fertilizer into cultivation soil, applying 25% of the nitrogenous fertilizer and 25% of the potassic fertilizer as primary topdressing fertilizer into the cultivation soil in a tillering stage, and averagely applying the rest of the nitrogenous fertilizer and the potassic fertilizer into the cultivation soil after each harvest process. Through selection of appropriate nitrogenous fertilizer, phosphate fertilizer and potassic fertilizer and reasonable collocation of the fertilizer use amounts, the method satisfies orchardgrass nutritional requirements, fully improves nutrient absorption of orchardgrass by the fertilization processes in growth earlier and later stages of orchardgrass, effectively improves orchardgrass quality and output, reduces energy consumption, avoids environmental pollution, improves soil fertility, and greatly improves economic benefits of orchardgrass production.
Description
The present patent application be for application number be 201110355876.4, the applying date is the divisional application of the patent of invention on November 10th, 2011.
Technical field
The present invention relates to the fertilizing method of a kind of orchardgrass, be specifically related to the fertilizing method of a kind of model orchardgrass.
Background technology
Orchardgrass claims again halymenia dentata, orchard grass, originate in Europe, north African and Temperate Region in China, Asia, it is one of world-renowned temperate zone good forage, the plantation history of existing more than 200 year in North America, being one of U.S. commerial growing herbage at present, is also one of good mixed seeding grass seeds of sylvan life meadow and high light efficiency sown pasture.
In recent years, orchardgrass is extensively cultivated application on China Sichuan, Chongqing, Shanxi, Gansu, Heilungkiang and other places, and has obtained certain economy, ecology and social benefit.But in plantation orchardgrass process, orchardgrass is not furtherd investigate, according to local soil fertility, the potassium balance of nitrogen phosphorus is joined and execute, thereby orchardgrass productivity and grass product matter are not high, also brought environmental pollution, orchardgrass cultivating economic benefit has much room for improvement.
Summary of the invention
The object of the present invention is to provide the fertilizing method of a kind of model orchardgrass.
The object of the invention is to realize by following technical measures, be below weight percentage, except special instruction:
A fertilizing method for model orchardgrass, is characterized in that: adopt urea (N content is 46%, is commercially available prod) as nitrogenous fertilizer, superphosphate (P

2o content is 25%, is commercially available prod) be potash fertilizer, wherein the consumption of nitrogen, phosphorus and potassium is for pressing N, P
2o
5, K
2o is than 1.986: 1: 2.114, in weight part ratio; First using whole phosphate fertilizer, apply in cultivating soil as base manure with 45% nitrogenous fertilizer and phosphate fertilizer, the nitrogenous fertilizer in tillering stage using 25% and potash fertilizer is as topdressing and apply for the first time, the nitrogenous fertilizer of residue 30% and potash fertilizer each harvesting afterwards mean allocation apply; State cultivating soil specifically, it is the types of soils of reservoir area of Three Gorges: brown paddy soil, soil property is sandy loam, soil nutrient status is: 0～20cm soil layer content of organic matter is 9.11%～10.02%, ammonium nitrogen 0.08g/kg～0.18/gkg, available phosphorus 0.253g/kg～0.531g/kg, available potassium 0.021g/kg～0.062g/kg, pH is 5～7; Described amount of application of nitrogen fertilizer is 522kg/hm
2, phosphate fertilizer amount is 667 kg/hm
2, K Amounts is 227 kg/hm
2.
Specifically, the fertilizing method of a kind of orchardgrass, carries out as follows:
(1) unit are amount of urea is 522kg/hm
2, superphosphate consumption is 667 kg/hm
2, potassium sulfate consumption is 227 kg/hm
2;
(2) in the previous day of planting, using whole phosphate fertilizer, 45% nitrogenous fertilizer and potash fertilizer as base manure and fine earth impose on equably cultivating soil railway carriage or compartment face after mixing, cover; Soil types: brown paddy soil, soil property is sandy loam, soil nutrient status is: 0～20cm soil layer content of organic matter is 9.11%～10.02%, ammonium nitrogen 0.08 g/kg～0.18g/kg, available phosphorus 0.253g/kg～0.531g/kg, available potassium 0.021g/kg～0.062/gkg, pH is 5～7;
(3) in tillering stage, using 25% nitrogenous fertilizer and potash fertilizer as topdressing and apply for the first time;
(4) after each harvesting, mean allocation applies the nitrogenous fertilizer and the potash fertilizer that remain 30%: when harvesting twice, use 15% at every turn; When harvesting three times, use 10% at every turn, the like.
Above-mentioned orchardgrass kind can be peace bar, Baoxing, model, Taurus, Chuan Dong, is preferably model orchardgrass.
The present invention has following beneficial effect:
The present invention is by selecting suitable nitrogen, phosphorus, potash fertilizer, thereby the consumption of reasonably combined nitrogen, phosphorus, potash fertilizer has met the nutritional need of orchardgrass well, and Fertilizers mode has fully improved the grow nutrient absorption of forward and backward phase of orchardgrass simultaneously; Accomplish well the balanced application to nitrogen, phosphorus, potash fertilizer in orchardgrass production, give full play to the fertilizer efficiency of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, quality and the output of orchardgrass are effectively improved, reduce energy resource consumption, avoided environmental pollution, improved soil fertility, greatly improved the economic benefit that orchardgrass produces.
