Problems solved by technology

At present, farmers generally use chemical fertilizers as the main fertilizer, and the proportion and application amount of each nutrient are relatively random. A reasonable fertilization technology system has not been formed. Long-term unreasonable fertilization will affect the healthy growth of green bamboo, resulting in the output of horseshoe shoots and the economic benefits of farmers. decline, affecting the sustainable development of horseshoe bamboo shoots industry

Embodiment 1

[0008] Embodiment 1, with 50% decomposed organic fertilizer, 10% urea, 20% superphosphate, 6% calcium magnesium phosphate fertilizer, 10% potassium sulfate, 3.9% silicon fertilizer, 0.1% sulfuric acid heptahydrate The special fertilizer for green bamboo can be obtained by co-extruding and granulating zinc. The fertilizer effect test is shown in the following table 1:

[0009] Fertilizer effect test 1: The test site is located in Kunyang Town, Pingyang County. The phylogenetic age of the bamboo clump is 10 years. There are 10-12 clumps of mother bamboo. The soil of the bamboo forest is pastoral soil. The basic fertility of the bamboo garden: organic matter 22.0g / kg, total nitrogen 1.67 g / kg, total phosphorus 0.54 g / kg, fast nitrogen 121mg / kg, fast phosphorus 68 mg / kg, fast potassium 40 mg / kg, pH value 5.08. Routine fertilization by farmers is mainly based on compound fertilizers. For example, 2.5 kg of compound fertilizers are applied every year, and the second application is ...

Embodiment 2

[0012] Embodiment 2, with 55% decomposed organic fertilizer, 10% urea, 15% superphosphate, 15% potassium sulfate, 4.9% silicon fertilizer, 0.1% zinc sulfate heptahydrate mixed extrusion granulation Get special fertilizer for green bamboo.

[0013] Fertilizer effect test 2: The test site is located in Qiaodun Town, Cangnan County.

[0014] 12-18 mother bamboos, the soil of the bamboo forest is sandy loam, the basic fertility of the bamboo garden: organic matter 24.0g / kg, total nitrogen 2.12 g / kg, total phosphorus 0.74 g / kg, rapid nitrogen 141mg / kg, rapid phosphorus 88 mg / kg , fast potassium 80 mg / kg, pH value 5.38.

[0015] Select bamboo clumps with relatively consistent bamboo forest structure and growth conditions to carry out the experiment, 5 clumps per treatment, and repeat 5 times. The test is carried out on the principle that the total amount of N, P, and K applied is basically the same, and the amount of fertilizer is appropriately adjusted according to the size of the...

Embodiment 3

[0018] Embodiment 3, with 45% decomposed organic fertilizer, 12% urea, 25% superphosphate, 14.9% potassium sulfate, 3% silicon fertilizer, 0.1% zinc sulfate heptahydrate mixed extrusion granulation Get special fertilizer for green bamboo.

[0019] Fertilizer effect test 3: The test site is located in Guanmei Town, Cangnan County. The phylogenetic age of bamboo bushes is 5 years old.

[0020] 6-8 bamboo plants, the soil of the bamboo forest is sandy loam, the basic fertility of the bamboo garden: organic matter 16.8g / kg, total nitrogen 0.92 g / kg, total phosphorus 0.28 g / kg, rapid nitrogen 63.7mg / kg, rapid phosphorus 2.6 mg / kg , fast potassium 80 mg / kg, pH value 4.66.

[0021] Select bamboo clumps with relatively consistent bamboo forest structure and growth conditions to carry out the experiment, 5 clumps per treatment, and repeat 5 times. The test is carried out on the principle that the total amount of N, P, and K applied is basically the same, and the amount of fertilizer i...

Abstract

The invention relates to a special fertilizer for bambusa oldhami, which comprises the following components in percentage by weight: 45-55% of well-rotted organic fertilizer, 10-15% of urea, 10-30% of calcium superphosphate, 0-10% of calcium-magnesia phosphate fertilizer, 8-15% of potassium sulfate, 3-5% of silicon fertilizer and 0.1% of zinc sulfate heptahydrate. By using the special fertilizer for the bambusa oldhami, nutrients needed by the growth of the bambusa oldhami can be supplied completely; the improvement of soil fertility can be achieved; the contents of organic matters in soil are improved; and the high and stable yield of the bambusa oldhami is achieved.

Description

technical field [0001] The invention relates to a special fertilizer for green bamboo. Background technique [0002] Green bamboo is a well-known fine edible bamboo shoot species in southern my country. Because its bamboo shoots are shaped like horseshoes, they are commonly called "horseshoe shoots". Horseshoe bamboo shoots are mainly produced in southern Zhejiang, Fujian and Taiwan, with a total area of ​​about 400,000 mu. Different from the scattered bamboo shoots such as moso bamboo shoots and thunder bamboo shoots that come out in winter and spring, horseshoe shoots are mainly produced in June to October in my country, which just fills the gap in the season when other bamboo shoots are on the market. The benefits are very high. The area increases at a faster rate. Horseshoe bamboo shoots are the treasures of bamboo shoots. They have thin shells and thick flesh, thick and white, crisp and tender texture, sweet and refreshing, rich in nutrition, and cool in nature. Accor...
