Composting method for natural fertilizer special for kiwi fruit

Abstract

The invention discloses a composting method for a natural fertilizer special for a kiwi fruit. The method comprises the following specific steps of: digging a crossed ventilation groove on a garden field; piling plant raw materials such as abandoned branches, fallen leaves, mountain weeds, shrub shoots, crop straws and the like in a garden and human and livestock manure alternatively on the ventilation groove; covering and sealing with a black light-tight plastic film; and heating and fermenting a compost for 3-8 months till the compost is turned into powder. The method has the beneficial effects that: the black light-tight plastic film is used for covering, so that the effects of preserving moisture and preserving high temperature are achieved; uprising air stream can be formed on the crossed ventilation groove, so that a compost body is ventilated passively for fully fermenting; all raw materials are taken locally, so that the natural properties of raw materials are ensured; and moreover, active ingredients in the fertilizer and a mixture ratio of the active ingredients are consistent with a nutritional structure needed by a fruit, so that the original ecological nature of fruits is kept, the use of farm chemicals and chemical fertilizers which damage an ecological environment or damage the health of people can be avoided, and product quality is enhanced.

Description

technical field [0001] The invention relates to a method for producing fertilizer, in particular to a method for composting special natural fertilizer for kiwifruit. Background technique [0002] Kiwifruit is a kind of vine fruit, which has a long history of cultivation in my country, and is generally distributed in the warm zone of 23°-34° north latitude and the northern subtropical mountains. Its fruit is rich in nutrition, with a total sugar content of 8%-14%, mainly glucose, followed by fructose. The acidity is high, the total acidity is 1.2%-2.0%. It also contains 12 kinds of amino acids, rich in protein and minerals such as calcium, phosphorus, potassium and iron, and is one of the most nutritious fruits. Because kiwi fruit is comprehensive and rich in nutrition and contains some important substances that are indispensable to the human body, it plays an important role in maintaining human health, preventing and curing diseases; eating more kiwi fruit can prevent oste...

Problems solved by technology

[0003] In order to increase production and improve quality, fertilizers are generally applied. At present, known fertilizers are generally chemical fertilizers such as N, P, and K, or organic fertilizers, or organic-inorganic compound fertilizers. These fertilizers are indeed good for increasing kiwi fruit production. However, its adverse effects are also very large. First, long-term use will cause soil compaction and a serious decline in fertility, which is very unfavorable to the ecological environment; secondly, it will also have a serious impact on the quality of kiwi itself. Irregularity; and there are residues of ordinary chemical fertilizers, which pose a potential threat to people's health

[0004] Patent application No. 200510021550.2 announced "kiwifruit special foliar fertilizer", which is mainly obtained by effectively compounding nutrients such as nitrogen, phosphorus, potassium, boron, zinc, iron and humic acid required for the growth and development of kiwifruit; patent application No. 200910022116.4 announced the "Special Fertilizer for Kiwifruit and its preparation process", which is made by oxidizing and modifying humic acid to become humate and adding nitrogen fertilizer, phosphate fertilizer and potassium fertilizer; It is good for the yield, but it will have a negative impact on the quality of the fruit and the quality of the soil
