Set fertilizer suitable for Xishuangbanna bananas

Abstract

The invention discloses set fertilizer suitable for Xishuangbanna bananas. The set fertilizer solves the problem that the fertilization effect of the Xishuangbanna bananas is poor. The set fertilizer comprises an early-stage set fertilizer body, a middle-stage set fertilizer body and a later-stage set fertilizer body. The early-stage set fertilizer body comprises urea, ammonium sulfate, liquid ammonia, sulfuric acid, ammonium phosphor nitrate, monoammonium phosphate, potassium sulphate and magnesium sulfate. The middle-stage set fertilizer body comprises sulfuric acid, liquid ammonia, potassium chloride, phosphoric acid, zinc sulphate monohydrate, borax and manganese sulfate monohydrate. The later-stage set fertilizer body comprises liquid ammonia, sulfuric acid, monoammonium phosphate, potassium sulphate and monocalcium phosphate. The components and types of the fertilizer bodies at the three stages are configured and matched with the soil property of the Xishuangbanna tropical rainy climate, soil unknown elements are provided by elementary substances or composite raw materials at different ratios at various stages for growth and development of the bananas, the absorption requirements of the bananas for N, Mg, P and K at the early stage, for N, P, K, B, Zn and Mn at the middle stage and for Ca, N, P and K at the later period are met, and it is guaranteed that the bananas which are green and high in quality and yield are produced.

Description

technical field [0001] The invention relates to a fertilizer, which belongs to the field of agricultural chemistry, in particular to a set fertilizer suitable for bananas in Xishuangbanna. Background technique [0002] Xishuangbanna has a tropical rainforest climate, and it is also an inland planting base developed after the typhoon disasters in Guangxi and Hainan banana planting bases. At present, the Xishuangbanna Tropical Rainforest Planting Base, with Jinghong City in Xishuangbanna as the axis, radiates to parts of Myanmar and Laos, where Southeast Asia and China have a tropical rainforest climate with a narrow strip of water. The planting area is more than 2 million mu, and its output accounts for 60% of the total banana output. %above. The banana industry has become a pillar agricultural industry in Xishuangbanna, Laos, Myanmar and the tropical rainforest climate of the Golden Triangle, and it is also the most important economic crop in the "Poppy Alternative Cultivat...

AI Technical Summary

Problems solved by technology

However, the tropical rainforest climate with Xishuangbanna as the axis has weak soil fertility, coupled with the washing and leaching of rainwater, the loss of fertilizer nutrients is serious, resulting in a serious lack of N, P, K and micro-elements in the soil. Therefore, the soil in this area provides The mineral nutrients of bananas are extremely limited and seriously deficient, which also affects the improvement of banana yield and quality to a large extent.

[0004] At present, my country has a fully water-soluble macronutrient package fertilizer and a single banana-specific fertilizer, but there is no package compound fertilizer suitable for all stages of banana growth and development.

The water-soluble large-element package fertilizer is only suitable for raising seedlings in the early stage. Bananas need a large amount of fertilizer in the middle and late stages, and the fertilizer effect is required to be stable and long-lasting. However, the large-element water-soluble fertilizer dissolves quickly, releases nutrients quickly, and has serious penetration, loss, and evaporation. , resulting in short fertilizer effect time and extremely low utilization rate, which cannot meet the needs of bananas in the middle and late stages of mineral nutrients.

Traditional banana-specific fertilizers generally use a balanced ratio or high-nitrogen and high-potassium type. It is only a ratio that is applied to the end, which cannot meet the needs of N, P, and K at each stage of banana growth and development. Therefore, it causes insufficient N in the early stage. , which is unfavorable to vegetative growth and delays the flower bud differentiation period; excess K will increase investment costs and waste resources, and excess N in the later period and insufficient K will cause broken buds, low quality of cracked fruit, and severe production reduction
