Abstract

Bamboo forest bagged fertilizer with multiple controlled-release formulas includes a bag A and a bag B. Each of the bag A and the bag B has three weight specifications, namely about 100g, 200g and 300g. The bag A is formed by mixing of, by weight, 72-88 parts of urea, 27-33 parts of potassium sulphate, 63-77 parts of calcium magnesium phosphate and 1.6-4 parts of dicyandiamide. The bag B is formed by mixing of, by weight, 117-143 parts of urea, 36-44 parts of potassium sulphate and 27-33 parts of diammonium phosphate. The bag A is more quick-acting than the bag B, and the bag B has better controlled-release effect. A fertilizing method of the bagged fertilizer includes 1, determining fertilization objects, 2, selecting fertilization time, 3, selecting proper climate, 4, arranging and digging fertilizer burring caves and 5, determining fertilization amount. The bamboo forest bagged fertilizer has the advantages that when the fertilizer is applied to bamboo forests, quick action and controlled release are combined, and accordingly, balance and high efficiency are achieved; each bamboo shoot needs fertilization once for its all life, so that fertilization amount is few, workload is small, utilization rate of the fertilizer is increased, and non-point source pollution of the fertilizer to environment is reduced; bamboos grow vigorously, and fertilizer and pesticide reduction for high-efficiency bamboo forest cultivation is achieved.

Description

The bamboo grove packed fertilizer of multi-control controlled-release formulation and fertilizing method thereof

Technical field

The present invention relates to a kind of composting of forestry, fertilizing method, the packed fertilizer of formula of specifically arranging in pairs or groups for the quick-acting of bamboo grove and slowly-releasing and fertilizing method thereof.

Background technology

Bamboo value of exploiting and utilizing is high: bamboo shoots are high microsteping, low-fat Forest food; Bamboo wood can be made into various product, of many uses; In addition, high, the solid carbon ability of bamboo ornamental value is strong, is the species economic, ecological, social benefit is all good.Current global bamboo wood output 2000-2500 ten thousand tons, estimates 21 century Mo Keda 5500-6500 ten thousand tons.Bamboo for the whole world more than 500,000,000 hundred million people the important source of income is provided.In state-owned more than 3,000 ten thousand populations are all or part of from bamboo grove and bamboo Product processing, obtain living expenses, wherein more than 750 ten thousand people are directly engaged in bamboo forest cultivation, bamboo wood and bamboo shoot process industry, and there is 1/4-1/3 in the year of peasant household of bamboo district from bamboo in income.Since the eighties in 20th century, along with the development of market economy, under the promotion of scientific-technical progress and develop bamboo by science, China Bamboo Industry is developed rapidly, form one by Resource Cultivation, processing and utilization to the new industry of the export trade, become the large sunrise industry of four in China's Forestry Development together with flower industry, Forest Tourism, Forest food industry, and bamboo has more development space and developing potentiality.
