Special organic fertilizer for Kiwi berry and preparation method thereof

Abstract

The invention provides a special organic fertilizer for a Kiwi berry and a preparation method thereof, belonging to the field of organic fertilizer. The special organic fertilizer is prepared from the following raw materials: kitchen waste, soybean straw, cassava waste, bamboo charcoal, a composite microbial agent, humic acid, montmorillonite and sulfur powder, wherein the raw materials are scientifically proportioned according to the nutritional demands of Kiwi berry. The preparation method comprises the following steps: fermentation of the raw materials; mixing of the sulfur powder and bamboo charcoal; and preparation of a finished product, i.e., the special organic fertilizer. The special organic fertilizer for Kiwi berry has high biological activity, good absorption performance and long-lasting fertilizer efficiency and is capable of effectively improving the rhizosphere environment of the Kiwi berry. Moreover, through integrated action of fertilizer-efficiency elements and microbes, the fertilizer can prevent chlorosis and canker of the Kiwi berry and improve the output and quality of the Kiwi berry.

Description

technical field [0001] The invention belongs to fertilizers, and more specifically to organic fertilizers, in particular to special organic fertilizers for kiwifruit. Background technique [0002] Kiwifruit (scientific name: Actinidia chinensis Planch), also known as kiwifruit (kiwifruit is an artificially selected variety of kiwifruit, which has become a synonym for kiwifruit because of its wide use), the fruit shape is generally oval, the early appearance is green-brown, mature It is reddish-brown, with densely downy skin, edible, and inside is bright green flesh and a row of black or red seeds. Because macaques like to eat, it is named kiwi fruit; it is also said that it is named because the skin is covered with hair and looks like a macaque. It is a fresh, tender, nutritious and delicious fruit. [0003] In recent years, as the market demand has increased year by year, the planting area of ​​kiwifruit has continued to grow. However, due to the high nutritional demand of...

AI Technical Summary

Problems solved by technology

[0003] In recent years, as the market demand has increased year by year, the planting area of ​​kiwifruit has continued to grow. However, due to the high nutritional demand of kiwifruit during growth and development, annual pruning and fruit picking will take away a large amount of nutrients, which cannot be replenished in time during management. The imbalance of elements leads to various diseases, coupled with the perennial use of chemical fertilizers, resulting in soil compaction, poor air permeability, soil biological activity is inhibited, and soil pH cannot be properly adjusted, which reduces the effective nutrients in the soil and absorbable mineral elements such as sulfur, The lack of absorbable mineral elements such as iron affects the synthesis of phenolic substances, amino acids, proteins and other substances that enhance physiological resistance in kiwifruit, resulting in serious yellowing of kiwifruit leaves and frequent occurrence of cankers

In addition, a large increase in water during irrigation will easily cause calcium carbonate to react with carbon dioxide to form bicarbonate, which will also aggravate the occurrence of iron-deficiency chlorosis

[0004] From the actual production situation, paying attention to the cultivation of soil fertility during the fertilization stage, strengthening the activities of soil organisms, forming a good soil micro-ecological environment, and increasing the supply of soil available nutrients are effective measures to ensure the good growth and high-quality production of kiwifruit, but now The biological activity of the organic fertilizer used is not high, the pertinence of beneficial bacteria is not strong, the absorption efficiency of chemical fertilizer is not high, and it also brings many problems, such as a kind of organic-inorganic compound specially used for kiwifruit with patent number CN201110325005.8 Fertilizer and preparation method thereof can improve product quality, increase yield, and improve fertilizer utilization efficiency

However, this invention lacks targeted microorganisms to improve the soil environment, and the sulfur content in the mineral elements is low, which is obviously insufficient in improving the disease resistance of kiwifruit
