Problems solved by technology

At present, there is no standard fertilization technology for "Shuicheng kiwifruit". Some growers use self-made farmyard manure, and some use commercial organic fertilizer, and there is no soil test and formula fertilization for the application of N, P, and K fertilizers, or use The proportion of the compound fertilizer is aimed at general crops, resulting in the simultaneous existence of nutrient deficiency and excess in the current orchard, which directly affects the yield and benefit of kiwifruit in Shuicheng County.

Embodiment 1

[0022] Take the production of 1000kg of Shuicheng kiwifruit special fertilizer as an example: 100kg of cattle manure (on a dry basis), 90kg of oil keratin (on a dry basis), 10kg of sawdust, 270kg of urea, 280kg of diammonium phosphate, 240kg of potassium sulfate, and biosynergistic 10kg of the agent is dried, pulverized, sieved and mixed.

[0023] In Erga Village, Miluo Town, Shuicheng County, Guizhou Province, the fertilizer effect test of Shuicheng kiwifruit special fertilizer was carried out. The test site was a 3-year-old kiwifruit orchard, and the control, conventional compound fertilizer (18-18-18) and special fertilizer were used. Refer to Shuicheng County For medium kiwi fruit yield and fertility level, 1 kg of compound fertilizer and special fertilizer is applied per plant, and it is applied in holes in the first ten days of December 2018 and mixed with soil. Each treatment was repeated 3 times, and a total of 9 plots were randomly arranged. The area of ​​the plot is...

Abstract

The invention discloses a special fertilizer for kiwifruits in Shuicheng. The special fertilizer consists of three major elements, namely organic matters, nitrogen, phosphorus and potassium, and a biological synergist, wherein the effective contents of the three major elements of nitrogen, phosphorus and potassium are calculated according to N, P2O5 and K2O, the weight part of N is 15-22, the weight part of P2O5 is 12-18, the weight part of K2O is 4-11, and the weight part of organic matter is 15-25; the weight part of the biological synergist is 0.7 to 1.5 parts; wherein the nitrogen, phosphorus and potassium are respectively derived from urea, diammonium phosphate and potassium sulfate, the organic matters are animal manure, oil cake and sawdust, and the effective viable count of the biological synergist is more than or equal to 200 million / g. According to the method, the fixed phosphorus element is liberated through humic acid, redundant potassium ions are absorbed and stored, environmental pollution and crop productivity reduction caused by excessive use of the potash fertilizer are reduced while the nutritional requirements of the kiwifruits are met, and the yield of the kiwifruits in the Shuicheng is increased.

Description

technical field [0001] The invention relates to a special fertilizer for kiwifruit, in particular to an organic-inorganic compound formula fertilizer suitable for the cultivation of kiwifruit in Shuicheng karst mountains.
