Organic water-fertilizer for prompting high yield of pearl guava

Abstract

The invention relates to the field of agricultural organic fertilizers, and discloses an organic water-fertilizer for promoting high yield of pearl guava. A preparation method of the organic water-fertilizer comprises the following steps: retting 5 to 10 percent of dried small shrimps, 15 to 20 percent of fishbone, 15 to 20 percent of diatomaceous earth, 20 to 40 percent of bran, 10 to 20 percent of rice stem, 1 to 3 percent of EM (Effective Microorganism) bacteria liquor and 5 to 10 percent of flaccid knotweed herb; stirring and mixing animal urine, the retted materials and water. The water-fertilizer is slightly applied to seedlings of the pearl guava, so that the problems of soil hardening, low fertility of applied organic fertilizers and existence of pathogenic bacteria due to inconvenience in fertilization and application of an inorganic fertilizer in the conventional planting and fertilizing process of the pearl guava are solved.

Problems solved by technology

[0002] Pearl guava, the meat is very soft, the gravy is rich, the taste is sweet, almost seedless, the fruit is oval, the color is milky green to milky white, it is extremely beautiful, it contains a lot of potassium, iron, carotene, etc., and it is extremely rich in nutrition. The favorite fruit of consumers, pearl guava is easy to cultivate, and it is not easy to lack fertilizer, but applying organic fertilizer at the seedling stage can speed up the growth of pearl guava fruit trees. The commonly used organic fertilizer is animal manure, but animal manure contains In addition to a lot of organic matter, there are also many pathogenic bacteria, especially root-knot nematodes. Guangxi is located in the south of China, with a mild and humid climate, which is suitable for the growth and reproduction of pathogenic bacteria, especially root-knot nematodes. Root-knot nematodes are common diseases and insect pests of guava. There are many pathogens of root-knot nematodes, which are highly contagious, and the transmission channels are complex, so it is difficult to control. The growth of guava fruit trees infested by root-knot nematodes is weak, and the symptoms are similar to drought and lack of fertilizer and water. It is dull and easy to fall off, and the branches will wither. In severe cases, the whole plant may die. Fertilization can also use inorganic fertilizers, such as potassium dihydrogen phosphate, urea, etc. Improper use of inorganic fertilizers will lead to land compaction

In the process of fertilizing solid fertilizer, the labor intensity will be greater, and it is easy to volatilize. It will volatilize before the fruit tree can absorb it in the future, which is not conducive to the absorption of trace elements.

[0003] At present, in the planting process of pearl guava, there is a method of applying water and fertilizer to improve the quality of guava fruit. For example, Chinese patent CN 102487772 B discloses a planting method for improving the quality of pearl guava fruit. The composition of the soluble fertilizer utilized is: urea, potassium nitrate, monoammonium phosphate, amino acid, calcium nitrate, zinc sulfate, borax, magnesium sulfate, this invention uses inorganic fertilizer as fertilizer but the use of inorganic fertilizer will cause land compaction, which is not conducive to Regrowth of fruit trees in an orchard

Therefore, in the current guava plantation and fertilization process, there will be inconvenience in fertilization, the application of inorganic fertilizers will cause soil compaction, and the application of organic fertilizers will cause low fertility and contain pathogenic bacteria.
