Preparation method of jatropha curcas mycorrhizal fungus compound fertilizer

Abstract

The invention discloses a preparation method of jatropha curcas mycorrhizal fungus compound fertilizer. The preparation method comprises the following steps: squeezing and dehydrating a composition composed of banana straw and rice straw in a volume ratio of 1: (1-4) by using a squeezing and crushing machine, cutting into pieces, and airing; mixing the air-dried fragments with poultry manure and amicrobial agent, adding the mixture into an anaerobic tank, turning and fermenting, adding a deodorant after fermentation is completed, stirring by a stirrer, crushing by a crusher, drying, and sieving by a 100-120-mesh sieve to obtain fermented and decomposed fertilizer powder for later use; mixing calcium superphosphate, monopotassium phosphate and borax, grinding for 20-40 minutes, and sievingwith a 120-140-mesh sieve to obtain mixed powder; and mixing the fermented and decomposed fertilizer powder and the mixed powder, and granulating to obtain a fertilizer with the particle size of 3mm-4mm, namely the jatropha curcas mycorrhizal fungus compound fertilizer.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a method for preparing a jatropha mycorrhizal compound fertilizer. Background technique [0002] Energy security is a major issue for China's national security and national economic development. It is imminent to find new environmentally friendly alternative energy sources for oil. Jatropha curcas is a multi-purpose tree species that is resistant to drought and barrenness. Both branches and leaves can be used, and the oil content of its seeds is 35% to 40%. Especially the crude fat mixture obtained by pressing from the seeds is an ideal environment-friendly mechanical fuel through chemical transformation. The advantages of "competing for land and not competing with others for food" have been widely recognized by the government and enterprises. However, during the current industrial development and planting of Jatropha curcas, due to poor soil, high temperature and dr...

[0002] Energy security is a major issue for China's national security and national economic development. It is imminent to find new environmentally friendly alternative energy sources for oil. Jatropha curcas is a multi-purpose tree species that is resistant to drought and barrenness. Both branches and leaves can be used, and the oil content of its seeds is 35% to 40%. Especially the crude fat mixture obtained by pressing from the seeds is an ideal environment-friendly mechanical fuel through chemical transformation. The advantages of "competing for land and not competing with others for food" have been widely recognized by the government and enterprises. However, during the current industrial development and planting of Jatropha curcas, due to poor soil, high temperature and dry air, many places Most farmers even use a single nitrogen or phosphorus fertilizer as base fertilizer or top dressing. Although some large-scale planting bases also use some compound fertilizers, the effective nutrient ratio of nitrogen (N), phosphorus (P) and potassium (K) is unscientific , the fertilizer supply is unbalanced, the fertilizer effect cannot be fully absorbed and soil improvement cannot be promoted, and there is no special compound fertilizer suitable for the characteristics of different growth periods of Jatropha curcas, resulting in poor crown growth of Jatropha curcas, late fruit bearing, less fruit bearing, small fruit, Oil content and other issues, so the output is often low, Jatropha oil, compared with tea oil, smooth skin oil, tung oil, has the highest economic properties in the production of biodiesel, therefore, how to increase the output of Jatropha curcas, scientific Fertilization is an urgent problem to be studied and solved in production

[0003] The invention patent of Chinese patent CN103724082B discloses a special fertilizer for Jatropha curcas, which consists of the following parts by weight: 20-30 parts of urea, 20-30 parts of superphosphate, 6-10 parts of potassium sulfate, and 10 parts of sulfur ~ 15 parts, 30 parts ~ 35 parts of borax, Jatropha curcas special fertilizer is applied during the growth period of Jatropha curcas plants, in the first year of Jatropha curcas growth period, at a distance of 25cm ~ 35cm from Jatropha curcas plants, Jatropha curcas Apply 160g-200g of special fertilizer; in the second year of Jatropha curcas growth period, apply 350g-400g of Jatropha curcas special fertilizer at a distance of 45cm-55cm from the Jatropha curcas plant; in the third year of Jatropha curcas growth period and later, At a distance of 45cm to 55cm from the Jatropha curcas plant, 550g to 630g of Jatropha curcas special fertilizer is applied, but the fertilizer efficiency of this special fertilizer is low, the tree growth is slow, and the fruit quality is not very satisfactory;

[0004] Chinese patent CN101913929B discloses a compound base fertilizer for Jatropha curcas, which contains nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer, and also contains 0.1% to 1.0% of amino acid chelated rare earth, 15% to 30% of Nitrohumic acid, 0.55% ferrous sulfate, 0.4% disodium tetraborate, 2% manganese sulfate, 0.5% copper sulfate, 0.25% zinc sulfate, 0.2% ammonium heptamolybdate, in compound base fertilizer The total N content is 11%~13%, the effective P 2 o 5 The content is 5.5%~6.5%, K 2 O content is 6.5%~7.5%, but the Jatropha curcas compound base fertilizer that this invention prepares has added rare earth element, and the price is high, and market application prospect is bad
