Embodiment 1

[0031] The fertilizer is composed of the following ingredients in parts by weight: 15% of nitrogen, phosphorus and potassium inorganic nutrients, 30% of organic matter, 1% of medium and trace elements, and the number of effective viable bacteria is more than or equal to 20 million / g.

[0032] Mix and granulate nitrogen, phosphorus and potassium inorganic nutrients, organic matter, medium and trace elements and microorganisms in proportion, and set aside for use. Prepare humic acid, shell powder, chitosan, cyclodextrin and carboxymethyl cellulose in a mass ratio of 38:14:2:4:1 for use. After mixing chitosan, humic acid and shell powder, add cyclodextrin and appropriate amount of water to fully grind into a uniform paste. Mix carboxymethyl cellulose with an appropriate amount of water to form a transparent liquid so that it does not produce stratification. Slowly add the carboxymethyl cellulose solution to the above-mentioned paste while stirring, fully stir evenly, and form an...

[0034] The fertilizer is composed of the following ingredients in parts by weight: 15% of nitrogen, phosphorus and potassium inorganic nutrients, 30% of organic matter, 1% of medium and trace elements, and the number of effective viable bacteria is more than or equal to 20 million / g.

[0035] Mix and granulate nitrogen, phosphorus and potassium inorganic nutrients, organic matter, medium and trace elements and microorganisms in proportion, and set aside for use. Prepare humic acid, shell powder, chitosan, cyclodextrin, and carboxymethyl cellulose in a mass ratio of 40:20:3:5:2 for use. After mixing chitosan, humic acid and shell powder, add cyclodextrin and appropriate amount of water to fully grind into a uniform paste. Mix carboxymethyl cellulose with an appropriate amount of water to form a transparent liquid so that it does not produce stratification. Slowly add the carboxymethyl cellulose solution to the above-mentioned paste while stirring, fully stir evenly, and form a...

Abstract

The invention provides a multifunctional sustained-release compound fertilizer for planting of fruit trees. The multifunctional sustained-release compound fertilizer is prepared from an emulsion and fertilizer particles in the mass ratio being 1: (2-10), wherein the emulsion is prepared from humic acid, shell powder, chitosan, cyclodextrin and carboxymethyl cellulose in the mass ratio being (38-42): (14-32): (2-5): (4-7): (1-5); the fertilizer particles are prepared from inorganic ingredients containing nitrogen, phosphorus and potassium, organic matters, microorganisms as well as medium and trace elements, and the mass ratio of the inorganic ingredients containing nitrogen, phosphorus and potassium to the organic matters to the medium and trace elements is (15-40): (15-30): (1-2). The invention further provides a preparation method of the multifunctional sustained-release compound fertilizer for planting of the fruit trees. The multifunctional sustained-release compound fertilizer simultaneously has functions of effectively activating the soil, increasing the soil fertility and organic matters, promoting growth of root systems, releasing nutrient substances, inhibiting bacteria and holding water, the preparation process is simple, large-scale production is facilitated, and the multifunctional sustained-release compound fertilizer is applicable to planting of fruit trees at various growth stages.

Description

technical field [0001] The invention belongs to the technical field of slow-release fertilizers in fertilizers, and specifically relates to a multifunctional slow-release compound fertilizer for fruit tree planting and a preparation method thereof. Background technique [0002] With the development and application of modern agricultural technology, the use of chemical fertilizers has increased year by year, and improving the utilization rate and yield increase has become a hot spot in agricultural research. However, the fertilizer utilization rate is decreasing year by year, and the soil ecological environment is deteriorating, which poses a serious challenge to the sustainable development of agriculture. The development and application of multifunctional slow-release fertilizers have an important impact on the sustainable development of Chinese agriculture. [0003] Most of the existing slow-release fertilizers in my country use substances with good slow-release effect, ea...
