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 paddy rice leaf fertilizer, the special-purpose fertile and application of specifically a kind of rice leaf.
Background technology
Reformed and opened up to the outside world since 30 years, China's agricultural has obtained tangible progress, and we have supported the population that accounts for the world 22% with the arable land that accounts for the world 7%, is that grain per unit area yield or total grain output have all obtained achievement highly visible.Paddy rice is that the master of China's agricultural plants crop, adjustment and grain security to China's structure of agricultural production all play an important role, development through 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 paddy rice industry with Chinese characteristics.Yet along with growth in the living standard, people more and more pay close attention to the quality of paddy rice, and the process of Rice Production has also caused people's great attention, and the problem of food safety has been put in face of the government and the common people.This mainly is because in recent years, in the Rice Production process, people more and more rely on chemical fertilizer and agricultural chemicals, and excessive chemical fertilizer and agricultural chemicals cause the rural ecological environmental degradation of China, soil quality descends, and crop resistance weakens, and the yield and quality of paddy rice has all been produced disadvantageous effect, especially the application of chemical substance, the nutritive value of paddy rice is reduced greatly, mainly show to lack the necessary trace element of some human bodies, based on a kind of like this thinking, we are after through the field experiment in 2 years, it is special-purpose fertile to develop a kind of rice leaf, and it both can improve the output of paddy rice, also can improve the quality of paddy rice, increase the nutritive value of paddy rice, satisfy people's needs.
In recent years, it is found that chitosan can increase substantially the output of farm crop, Japan nearly has that 10,000 peasant is applied to chitosan in vegetables, paddy rice and the Tea Production.The research report is arranged, chitosan can improve the tolerance to cold of paddy rice, improve the quality of paddy rice, its degraded product oligochitosan, function with regulating plant growth, growth, breeding, diseases prevention and 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 the soil, and improves the base respiration intensity of soil, increases soil microbes biomass carbon nitrogen, quickens decomposition of soil organic matter, makes soil discharge more nutrient and is made for the thing utilization.
Summary of the invention
The present invention is directed to the problem that exists in present China Rice Production process, chitosan and some other benefit materials are mixed, it is special-purpose fertile to develop a kind of rice leaf, 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 rice leaf is special-purpose fertile, by weight, chitosan 2-5%, aminoacids complex 7-12% (is mainly free L-amino acid, wherein comprise Threonine, Xie Ansuan, methionine(Met), Isoleucine, phenylalanine, arginine, glycine, Methionin, Histidine etc., can adopt all things on earth amino acid fertilizer, the biological products such as aminoacids complex, the emerging L-type of Chengdu Pepsi amino acid that produce of great ripple), 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 a water, adds to 100%.
The amount nutritive element is calcium and magnesium in described, and in calcium and magnesium elements, their mass concentrations in special-purpose fertilizer are 1.5-3.5%, and they are 0.75-1.75% respectively at the mass concentration in the special-purpose fertilizer; In the amount nutritive element for and/or magnesium be to add in the special-purpose 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-purpose fertilizer are 0.5-1.0%, and they are 0.1-0.2% respectively at the mass concentration in the special-purpose fertilizer; Described micronutrient element iron, copper, zinc, molybdenum and manganese are that the form with their soluble salt adds in the special-purpose fertilizer.
Described tensio-active agent is Tween 20 or Tween 80.
The special-purpose fertilizer in described blade face sprays in the Rice Production process as a kind of effective arbitrary way outside the root fertilising, 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, it is special-purpose fertile to develop a kind of rice leaf, it not only can promote paddy growth, improve the ability of the former bacterium of paddy disease-resistant, can also promote paddy rice to absorb nutrient, improve the output of farm crop.The nutritive element that needs in the growth process of riceplant has 16 kinds, they not only constitute the living matter of paddy rice, and the various Metabolic activities of adjusting paddy rice, foliage application plays a very important role in the Rice Production process as a kind of effective arbitrary way of root fertilising.
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.Simultaneously, this product also includes various middle micronutrient elements, and as calcium, magnesium, iron, copper, zinc, molybdenum, manganese, boron etc., they are moietys of paddy rice body endoenzyme or coenzyme, can promote chlorophyll and proteinic synthetic, strengthens photosynthesis.Because metallic element can not stable existence in the more weak system of acidity, and strong acid solution is unsuitable for the growth of crop, so will handle to metallic element, the present invention selects for use EDTA as complexing agent and complexing of metal ion, form stable compound, and the existing effect of preserving moisture of tensio-active agent also has the auxiliary function that absorbs.

Effect of fertilizer
Table 4 foliage application is to the influence of paddy rice seed and stalk output
As known from Table 4, used the present invention can make the paddy rice yield of kernels on average increase by 10.01% in 2008, 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%.Crop growing state and output generally were lower than 2008, but used this foliage application still to make the paddy rice yield of kernels on average improve 10.84% owing to climate reasons in 2009, and amplification was greater than 2008; Stalk output on average improves 9.38%, and is suitable with 2008 annual production amplification.Effect of increasing production in 2009 is best remains embodiment 2, seed volume increase 14.20%, and stalk volume increase 12.27% illustrates that this invention has more obvious effects for the paddy rice yield of kernels under the raising adverse environmental factor.Although but it is pointed out that 2009 and use that foliage application causes paddy rice yield of kernels amplification to improve, absolute yield still is to be higher than 2009 in 2008, illustrates that the weather year's harvest still plays absolute effect to the output of crop.
