Background technology
Peanut is one of main oil crops of China, and its seed is fatty 50% one 58%, oil yield about 40~60%.Expressed oil gas flavor delicate fragrance be rich in unsaturated fatty acids, and acid number is lower, is a kind of fine edible oil.Except that oil expression, peanut can also be processed into multiple tasty food.Peanut cake after the oil expression contains protein about 50%, and fat is about 7%, and carbohydrate is about 24%, is good feed and fertilizer.After pulverizing, peanut stem leaf can be used as the feed of livestock.The living root nodule bacterium free nitrogen in can fixed air is scientifically planted peanut and is helped land fertility and improve constantly.The production of development peanut to edible oil and the food demand that satisfies the people, promotes animal husbandry development, increases soil fertility, and aspects such as increase grain yield all have great importance.
In the plantation of peanut, because farm organic fertilizer material source wretched insufficiency, the chemical fertilizer that tradition is used for peanut only adopts nitrogen, phosphorus, potassium etc. usually, is commonly called as large chemical fertilizer.And use large chemical fertilizer merely, trophic structure is unbalance, though in the growth of peanut, can play certain promoter action, but bring many drawbacks also for the plantation of peanut, the one, lack multiple in, the collocation of trace element, cause that crop is degeneration-resistant, cold-resistant, a little less than drought resisting and the diseases and insect pests resistance, and cause the various nutritional deficiency diseases of peanut and the excessive murder by poisoning of some element easily, influence the growth of peanut, the output of peanut is difficult to improve; The 2nd, because fertilizer structure is unreasonable and to the detrimentally affect of soil, cause the peanut process of growth illnesss such as stem rot, root rot, leaf spot, rust to occur, have a strong impact on the output and the quality of peanut; The 3rd, the peanut quality of plantation is poor, and seed is not full, and oil yield is low, and nutritive ingredient is few, and undesirable components exceeds standard, and its chemical ingredients and evaluation index rate of grade are low, and planting benefit is poor; The 4th, the long-term application large chemical fertilizer causes Soil degradation easily, and formation is hardened, and particularly applied nitrogen is excessive, also is easy to generate the pollution of soil and underground water source, therefore national clear and definite many nitrogen fertilizer applications of not advocating; Five are to use the large chemical fertilizer consumption big, and plantation drops into many, deficiency in economic performance.In existing technology, existing plant-growth regulator uses, but this conditioning agent production process is complicated, and cost is higher, and the peasant is difficult to accept, thereby is unfavorable for promoting the use of.
Summary of the invention
The purpose of this invention is to provide a kind of nutritive element complete, the collocation balance reasonable, not only can be used as base fertilizer, but also can be used for foliage-spray, and can promote peanut growth metabolism, balanced nutrients, enhancing photosynthesis, and then make that the peanut result is many, output is high, do not have the high-yield peanut nutrients of variation, quality better.
Realize that the technical scheme that purpose of the present invention is taked is: the present invention is according to the characteristics of peanut growth rhythm and desired nutritional key element, and need carry out the reasonably combined of various nutrient elements in conjunction with present soil structure improved addictive, it is that preparation of raw material by following weight parts forms: 25~28 parts in urea, 26~30 parts of potassium primary phosphates, 8~10 parts of vitriolate of tartar, 3~5 parts in nitrocalcite, 19~22 parts in sal epsom, 6~10 parts in zinc sulfate, 8~12 parts in ferrous sulfate, 0.1~0.3 part of ammonium molybdate.
The present invention on the basis of an amount of collocation nitrogen, phosphorus, potassic fertilizer, has rationally increased multiple microelement fertilizer according to the needs of peanut growth to nutritive factor, makes various nutrient elements such as containing nitrogen, phosphorus, potassium, calcium magnesium, zinc, iron, molybdenum in the nutrient substance.These elements are composition and activators of plurality of enzymes, can participate in processes such as the intravital carbon assimalation of crop, carbohydrate transhipment, nitrogen metabolism and redox, promote growth, growth, the enhancing antibiosis of peanut.
The effect of contained each the effective nutritive element of the present invention in the peanut growth is respectively:
(1) urea: nitrogen element wherein is to promote plant growth, changes the leaf look fast, increases the main fertile of crop yield, can improve the nutritive value of crop, can increase the protein content in the seed especially, improves the quality and the nutritive value of peanut.
(2) potassium primary phosphate and vitriolate of tartar: collocation mutually, wherein is furnished with an amount of phosphorus and potassium according to the needs of peanut growth, phosphorus is the moiety of cellular plasm in making object, the growth and the propagation of pair cell play an important role, also participate in the photosynthesis of crop vital process and the transmittance process of energy, can improve the quality of crop, and can impel well developed root system, the crop precocity of crop, also can strengthen cold-resistant, the drought-resistant ability of crop; Potassium can promote the absorption of crop to nitrogenous fertilizer, helps proteinic synthesizing, and impels the plant growth stalwartness, output height, quality better.
(3) nitrocalcite: contain nitrogen and calcium, wherein calcium is the moderate-element that plant growth needs, and can promote the root system of crop to increase, and is beneficial to crop to nutrient absorbing, also can strengthen cold-resistant, the drought-resistant ability of crop.
(4) zinc sulfate: wherein contained zinc element is the moiety of some enzymes, and the hydration of catalysis plant carbonic acid gas is arranged, and strengthens photosynthetic function, respiratory function and the resistance of plant, can promote chlorophyllous conversion of synthesizing with carbohydrate.
(5) ferrous sulfate: wherein contained ferro element is the component of some enzymes in making object, helps chlorophyllous formation, promotes nitrogen metabolism, and is in close relations with the intravital oxidation-reduction of crop, has the crop disease-resistant of enhancing ability, improves the effect of crop yield.
(6) ammonium molybdate: contained molybdenum element can promote the nitrogen fixation of crop root nodule bacterium, also can improve the nitrogen content of soil simultaneously, is used for peanut cultivation, the lateral root of peanut is increased more than the twice, and improve the output and the quality of peanut thus.
(7) sal epsom: be a kind of efficient, Gao Rong, sulfur-bearing, magniferous fertilizer, wherein contained sulphur, magnesium are the element of heavyweight nutrition, and is necessary by increasing crop yield, upgrading, and different acidity or alkaline soil played fluffing action.Magnesium is chlorophyllous important composition, it is must be little for photosynthesis, and magnesium elements is the activator of many enzymes, can promote synthetic, the phosphatic conversion etc. of metabolism, the nucleic acid of carbohydrate.
The peanut nutrients that adopts above-mentioned raw materials to make, its beneficial effect is:
(1) nutritive element is complete, collocation rationally, can prevent excessive murder by poisoning of element and nutritional deficiency illness effectively, resist the infringement of various sick worms, strengthen cold-resistant, the drought-resistant ability of peanut, promote the growth of peanut effectively, make its result many, full grains, output improves more than 25%, and ripe early, quality better.
(2) both can be used as base fertilizer, also can be used for foliage-spray, under the situation that improves output, quality, can reduce fertilizer amount, and cost had been low, can reduce planting cost effectively, increased the plantation income.
(3) because in multiple, the coordinated balance of trace element, thereby can prevent hardening and the decline of barren property of soil effectively, and help the benign cycle of water and soil environment.
