Abstract
The invention provides a fertilizing method of forage grass. According to the fertilizing method, urea is taken as a nitrogen fertilizer, calcium superphosphate is taken as a phosphorous fertilizer and potassium sulfate is taken as a potassium fertilizer, wherein the use amounts of nitrogen, phosphorous and potassium are metered in parts by weight according to a ratio of N to P2O5 to K2O being 1.986 to 1 to 2.114. The fertilizing method comprises the following steps of firstly, applying all the phosphorous fertilizer and 45% of the nitrogen fertilizer and the potassium fertilizer taken as base fertilizers into culture soil; applying 25% of the nitrogen fertilizer and the potassium fertilizer taken as first time topdressing at a tillering stage; and averagely distributing and applying the residual 30% of the nitrogen fertilizer and the potassium fertilizer after each time of harvesting. According to the fertilizing method provided by the invention, the suitable nitrogen fertilizer, phosphorous fertilizer and potassium fertilizer are selected to be reasonably matched with the use amounts of the nitrogen fertilizer, the phosphorous fertilizer and the potassium fertilizer so as to meet nutrition requirements of orchard grass very well; meanwhile, a fertilizing manner is matched to sufficiently improve the nutrition absorption of prior periods and post periods of the orchard grass; the quality and the yield of the orchard grass are improved effectively; the energy source consumption is reduced, the environmental pollution is avoided and the soil fertility is improved, so that the economic benefits of production of the orchard grass are improved greatly.
Description
The present patent application is dividing an application for the patent of invention that application number is 201110355876.4, the applying date is on November 10th, 2011.
Technical field
The present invention relates to a kind of herbage fertilizing method, be specifically related to the fertilizing method of orchardgrass.
Background technology
Orchardgrass claims again halymenia dentata, orchard grass, originate in Europe, north African and Asia Temperate Region in China, 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 orchardgrass.
The objective of the invention is to realize by following technical measures, below be weight percentage, except special instruction:

2.
Specifically, the fertilizing method of a kind of orchardgrass, carry out as follows:
(1) the unit are amount of urea is 522kg/hm
2, the superphosphate consumption is 236kg/hm
2, the potassium sulphate consumption is 640kg/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 are sandy loam, and soil nutrient status is: 0～20cm soil layer content of organic matter is 9.11%～10.02%, ammonium nitrogen 0.08g/kg～0.18g/kg, available phosphorus 0.253g/kg～0.531g/kg, available potassium 0.021g/kg～0.062g/kg, pH are 5～7;
(3) in tillering stage, the nitrogenous fertilizer using 25% and potash fertilizer are as topdressing and apply for the first time;
(4) mean allocation applies and remains 30% nitrogenous fertilizer and potash fertilizer after each time harvesting: 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 the 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 the Fertilizers mode has fully improved the nutrient absorption of orchardgrass forward and backward phase of growth simultaneously; Accomplished well orchardgrass produce in to the balanced application of nitrogen, phosphorus, potash fertilizer, given full play to the fertilizer efficiency of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, quality and the output of orchardgrass have effectively been improved, reduce energy resource consumption, avoided environmental pollution, improved soil fertility, greatly improved the economic benefit that orchardgrass produces.
