Problems solved by technology

They have made great progress in prolonging the fertilizer effect through the application of several coating materials, but they are still mainly composed of nitrogen, phosphorus, potassium and other large elements, which cannot well meet the needs of seedlings for medium and trace elements, and need to be supplemented separately. Increase the cost of fertilization, and at the same time, it is impossible to make corresponding adjustments to the physiological conditions of plants, soil quality and water source environment

Embodiment Construction

[0017] A water-retaining seedling-coated fertilizer, made of the following raw materials in parts by weight (kg): coconut peat 36, fly ash 22, fermented glutinous rice 12, monoammonium phosphate 9, potassium selenite 3, sodium alginate 2 , sucrose fatty acid ester 1.2, tangelo young fruit 43, dimethylformamide 0.5, methyl jasmonate 1.0, polyvinyl alcohol 1.5, 50% ethanol solution, 70% methanol solution, water.

[0018] The specific steps of the preparation method of the seedling-coated fertilizer for retaining water and life are as follows:

[0019] (1) Mix coconut bran, fly ash, and fermented glutinous rice and put them in the fermentation tank for retting and fermentation for 3 weeks. After the fermentation is completed, take out the fermentation material and dry it, and mix it with monoammonium phosphate and potassium selenite to obtain granules spare;

[0020] (2) Dry the young pomelo fruit in the sun and dry it at 50°C for 48 hours, take it out, crush it with a pulverize...

Abstract

The invention discloses a water-holding living-keeping nursery stock coated fertilizer. The fertilizer is prepared from, by weight, 36-38 parts of coco coir, 22-24 parts of flyash, 12-15 parts of fermented glutinous rice, 9-11 parts of monoammonium phosphate, 3-4 parts of potassium selenite, 2-3 parts of sodium alginate, 1.2-1.5 parts of sucrose fatty acid ester, 43-45 parts of tangelo fruitlet, 0.5-0.6 part of dimethylformamide, 1.0-1.2 parts of methyl jasmonate, 1.5-1.7 parts of polyvinyl alcohol, an appropriate amount of 50% ethanol solution, an appropriate amount of 70% methanol solution and an appropriate amount of water. On the basis of nutrient slow release, high adsorbability of carbon powder is matched with addition of a modified material, water in the root system region of nursery stock is held, water desorption in the nursery stock can be relieved well, growth vigor of the nursery stock is kept, and the survival rate of the nursery stock is increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a seedling-coated fertilizer that retains water and keeps alive. Background technique [0002] With the development of specialization, industrialization and scale of planting in our country, its requirements for fertilizers are constantly upgrading, while traditional fertilizers have restricted the sustainable development of planting industry due to their low nutrient utilization. The application of coated fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the coating materials have a single function and usually only have slow and controlled release. The effect does not take into account the functions of water absorption, antibacterial, anti-oxidation...
