Abstract
The invention relates to a rice leaf fertilizer, in particular to a special fertilizer for rice leaf surfaces and application thereof. The special fertilizer comprises the following components by weight: 2 to 5 percent of chitosan, 7 to 12 percent of composite amino acid, 1.5 to 3.5 percent of middle-weight nutrient element, 0.5 to 1.0 percent of trace nutrient element, 2 to 4 percent of ethylene diamine tetraacetic acid (EDTA) complexing agent, 0.2 to 0.5 percent of surfactant and the balance of water. The special fertilizer for leaf surfaces is of an effective supplement mode except root fertilization, is applied in the rice production process, and plays an important role; and 30 to 40 kilograms of special fertilizer is used in each mu.
Description
Technical field
The present invention relates to Rice Leaf fertilizer, specifically a kind of special fertilizer for rice leaf surfaces and application thereof.
Background technology
Reformed and opened up to the outside world since 30 years, China's agricultural makes significant progress, and we support the population in the Liao Zhan world 22% with the arable land that accounts for the world 7%, be that Per Unit Area Grain Yield or total grain output have all obtained achievement highly visible.Paddy rice is the main cultivation crop of China's agricultural, adjustment and grain security to China's structure of agricultural production all play an important role, through the development of over half a century, the yield and quality of China paddy rice has obtained large increase, especially 30 years of reform and opening-up, the Rice Production of China formed rice industry with Chinese characteristics.But along with growth in the living standard, people more and more pay close attention to the quality of paddy rice, the process of Rice Production has also caused people's great attention, and the problem of food safety has been put in face of government and the common people.This is mainly due in recent years, in Rice Production process, people more and more rely on chemical fertilizer and agricultural chemicals, and excessive chemical fertilizer and agricultural chemicals cause Chinese Ecological Environment to worsen, soil quality declines, crop resistance weakens, the yield and quality of paddy rice has all been produced to disadvantageous effect, especially the application of chemical substance, the nutritive value of paddy rice is reduced greatly, be mainly manifested in and lack the necessary trace element of some human bodies, based on so a kind of thinking, we are after the field experiment of 2 years, develop a kind of special fertilizer for rice leaf surfaces, it both can improve the output of paddy rice, also can improve the quality of paddy rice, increase the nutritive value of paddy rice, meet people's needs.
In recent years, it is found that chitosan can increase substantially the output of farm crop, Japan has 10,000 peasant nearly that chitosan is applied in vegetables, paddy rice and Tea Production.Studies have reported that, chitosan can improve the tolerance to cold of paddy rice, improve the quality of paddy rice, its degraded product oligochitosan, there is the function of regulating plant growth, growth, breeding, diseases prevention and the aspect such as disease-resistant, immune system response that can stimulating plant, produces the active substance with disease resistance, suppresses the formation of disease.In addition, chitosan can also be improved soil, improves the base respiration intensity of soil, increases soil microbes biomass carbon nitrogen, accelerates decomposition of soil organic matter, makes soil discharge more nutrient for crop utilization.
Summary of the invention
The present invention is directed to the problem existing in current China Rice Production process, chitosan and some other benefit materials are mixed, develop a kind of special fertilizer for rice leaf surfaces, it both can improve the output of paddy rice, also can improve the quality of paddy rice, improve the nutritive value of paddy rice, for the production of green rice provides some technical supports.
For achieving the above object, the present invention adopts following technical scheme:
A kind of special fertilizer for rice leaf surfaces, by weight, chitosan 2-5%, aminoacids complex 7-12% (is mainly free L-amino acid, wherein comprise Threonine, α-amino-isovaleric acid, methionine(Met), Isoleucine, phenylalanine, arginine, glycine, Methionin, Histidine etc., can adopt all things on earth amino acid fertilizer, letter ripple bio aminoacids complex, the products such as the emerging L-type of Chengdu Pepsi amino acid), middle amount nutritive element 1.5-3.5%, micronutrient element 0.5-1.0%, EDTA complexing agent 2-4%, tensio-active agent 0.2-0.5%, surplus is water, add to 100%.
Described middle amount nutritive element is calcium and magnesium, and in calcium and magnesium elements, their mass concentrations in special fertilizer are 1.5-3.5%, and they are 0.75-1.75% respectively at the mass concentration in special fertilizer; Middle amount nutritive element is and/or magnesium is to add in special fertilizer with their form of soluble salt.
Described micronutrient element is iron, copper, zinc, molybdenum and manganese, and in iron, copper, zinc, molybdenum and manganese element, their mass concentrations in special fertilizer are 0.5-1.0%, and they are 0.1-0.2% respectively at the mass concentration in special fertilizer; Described micronutrient element iron, copper, zinc, molybdenum and manganese are to add in special fertilizer with the form of their soluble salt.
Described tensio-active agent is Tween 20 or Tween 80.
Described blade face special fertilizer, as the effective arbitrary way of one outside root fertilising, sprays in Rice Production process, and usage quantity is every mu of 30-40 kilogram.
The present invention is on the basis of mechanism research, chitosan is mixed with aminoacids complex, micro-metals and other benefit materials, develop a kind of special fertilizer for rice leaf surfaces, it not only can promote paddy growth, improve the ability of Rice Resistance cause of disease bacterium, can also promote rice absorbing nutrient, improve the output of farm crop.The nutritive element needing in growth process of riceplant has 16 kinds, they not only form the living matter of paddy rice, and the various Metabolic activities of adjusting paddy rice, foliage application, as the effective arbitrary way of one of root fertilising, plays a very important role in Rice Production process.
The present invention, except containing chitosan, also has each seed amino acid, and amino acid can provide necessary nutrition for the growth of paddy rice, can also stimulate paddy growth.Meanwhile, this product also includes various Meso-and micro-nutrients, and as calcium, magnesium, iron, copper, zinc, molybdenum, manganese, boron etc., they are moietys of paddy rice body endoenzyme or coenzyme, can promote the synthetic of chlorophyll and protein, strengthens photosynthesis.Because metallic element can not stable existence in the weak system of acidity, and strong acid solution is unsuitable for the growth of crop, so will process metallic element, the present invention selects EDTA as complexing agent and complexing of metal ion, form stable compound, and the effect of the existing moisturizing of tensio-active agent also has the auxiliary function absorbing.

Effect of fertilizer
The impact of table 4 foliage application on Rice Seed and stalk output
As known from Table 4, within 2008, use the present invention can make Rice Seed output on average increase by 10.01%, stalk output increases by 9.37%, and that effect of increasing production is best is embodiment 2, seed volume increase 12.70%, stalk volume increase 11.40%.2009 due to climate reasons, and crop growing state and output is generally lower than 2008, but uses this foliage application still to make Rice Seed output on average improve 10.84%, and amplification is greater than 2008; Stalk output on average improves 9.38%, suitable with 2008 annual production amplification.What effect of increasing production in 2009 was best remains embodiment 2, seed volume increase 14.20%, and stalk volume increase 12.27%, illustrates that this invention has more obvious effect for improving Rice Seed output under adverse environmental factor.Although but it is pointed out that 2009 and use that foliage application causes Rice Seed output amplification to improve, absolute yield or 2008, higher than 2009, illustrate that Climate Type still plays absolute effect to the output of crop.
