Description
Technical field
The present invention relates to field of fertilizer manufacturing, particularly a kind of middle-and-low-yielding fields alfalfa special fertilizer and preparation and application process.
Background technology
Alfalfa (Medicago stativa L.) is Perennial legume forages, is also China and even the herbage variety of cultivated area maximum in the world.The advantages such as, quality better high due to its strong adaptability, output have the laudatory title of " King of Pasture ".China is the country of protein feed resources shortage, and development quality alfalfa grass meal has become a new technological industry of exploitation protein feed resource.
CN101099432A (CN200710055909.7) discloses a kind of alfalfa drought resisting, anti-freezing cultivating method, wherein having announced fertilization time is disposable all fertilizer that apply before soil cultivation, fertilizer can be composite fertilizer or unitary class fertilizer carries out proportioning, wherein, to execute N be 30～45kg, P to per hectare
2O
5Be 135～180kg, K
2O is 135～180kg; CN101904265A (CN201010233703.0) discloses a kind of cultivating method of alfalfa in low-salt and-alkali cultivated land, wherein mentioning combined seed and fertilizer drill ditches on the ridge and executes seed manure, seed manure is that the mixing of diammonium phosphate and vitriolate of tartar is fertile, and the amount of application of diammonium phosphate is 145kg/hm
2～155kg/hm
2, the amount of application of vitriolate of tartar is 45kg/hm
2～75kg/hm
2In the prior art of having announced, the applying fertilizer of alfalfa is all general commercially available general fertilizer, also there is no up to now the report about the alfalfa special fertilizer.
The Shandong Province is the important livestock industry producing region of China, is also the main plantation area of northern alfalfa.But be subjected to the impact of traditional planting layout and policy, alfalfa production base, Shandong Province is distributed in yellow riffle area more, and take middle-and-low-yielding fields as main, soil type mostly is mild or moderate saline-alkali soil, and the basic soil fertility of soil is on the low side, the preserve moisture and fertility ability; In the alfalfa production process, by the long-term excessive quick-acting chemical fertilizer of using of prior art, fertilizer nutrient this season utilization ratio is very low, utilization rate of nitrogen fertilizer only has 30～35%, phosphate fertilizer utilization efficiency is about 10～20%, potassium utilization rate is 35～50%, causes serious environmental pollution when bringing the tremendous economic loss.Therefore, according to soil property characteristics and the regulation of fertilizer requirement in Alfalfa Growing area, Shandong Province, provide a kind of middle-and-low-yielding fields alfalfa special fertilizer and preparation and application process.
Summary of the invention
Purpose of the present invention is intended to make up the deficiency of existing alfalfa production and application fertilizer technology, according to the regulation of fertilizer requirement of alfalfa and in the soil property characteristics in the soil fertility saltings such as low or plantation area, non-saltings, a kind of middle-and-low-yielding fields alfalfa special fertilizer and preparation and application process are provided.
