Special soil conditioner for sisal hemp and preparation method of soil conditioner

Abstract

The invention discloses a special soil conditioner for sisal hemp. The special soil conditioner is prepared from the following raw materials in parts by weight: 13.6-33.2 parts of dolomite powder, 63.6-85.8 parts of organic fertilizer and 0-4.8 parts of coco coir. The preparation method comprises the following steps: weighing the raw materials according to the special soil conditioner for sisal hemp; and mixing the raw materials to obtain the special soil conditioner for sisal hemp. The soil conditioner special for sisal hemp is rich in calcium and magnesium nutrient elements and organic fertilizer needed by sisal hemp, calcium and magnesium are in an active state, sisal hemp can easily absorb and utilize the soil conditioner, the requirement of sisal hemp for calcium and magnesium elements can be met, robust growth of sisal hemp is promoted, sisal hemp diseases caused by calcium and magnesium deficiency are reduced, the organic fertilizer contains complete nutrients, is rich in active substances, and can significantly promote the growth of sisal hemp. The soil conditioner is high in safety, sisal hemp roots can directly grow on the soil conditioner, fertilizer damage is avoided, the preparation method is simple and convenient, the price is low, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of soil conditioners, and more specifically relates to a special soil conditioner for sisal and a preparation method thereof. Background technique [0002] Sisal is a perennial tropical hemp plant of the Agave family. Its fibers are tough, elastic, strong in tension, acid and alkali resistant, and corrosion resistant. It is widely used in the production of ropes, canvas, rope cores, conveyor belts, and carpets. It is an important industrial and agricultural raw material in national defense, fishing and navigation, petroleum, industrial and mining, metallurgy, daily life and other industries. The world's agave hemp is mainly grown in Brazil, Tanzania, Kenya, Madagascar, Mexico and China. Chinese sisal is mainly planted in Zhanjiang, Guangdong, Yulin, Nanning, Guangxi, Changjiang and Dongfang, Hainan. Most of the soil in these areas is basalt and granite, developed from red soil in the fourth century, with s...

Problems solved by technology

However, sisal needs a huge amount of calcium, and ordinary organic-inorganic composite soil conditioners are difficult to meet the calcium demand of sisal, and the cost of soil conditioners with humic acid as the main raw material is relatively high, often requiring 2000-3500 yuan / ton

The benefit of sisal cultivation is not high, only 350-420 yuan per ton of sisal leaves, calculated on the basis of 8 tons per mu (higher yield, generally only 5 tons / mu), the output value per mu is only 3040-3360 yuan, so it should be used in the market Organic-inorganic composite soil conditioner can not meet the calcium requirement of sisal, and its high price also limits its application on sisal

Guangdong Nongken Fengshou Fertilizer Factory adopts the method of adding 20% ​​quicklime to the fermented organic fertilizer to make an organic-inorganic composite soil conditioner, which is specially used on sisal. However, adding 20% ​​quicklime will easily cause the nitrogen volatilization loss in the organic matter, and it is easy to cause The compaction of organic fertilizer is not conducive to the growth of sisal root system and the absorption of calcium and magnesium elements
