Special fertilizer for sago cycas, and preparation method and application thereof

Abstract

The invention discloses a special fertilizer for a sago cycas, which comprises following components in parts by weight: 40-50 parts of urea, 2-10 parts of starch, 15-20 parts of methanal, 15-30 parts of donkey bone meal, 5-15 parts of bagasse, 10-15 parts of amino acid, 50-70 parts of ferrous sulfate, 10-25 parts of calcium phosphate, 10-25 parts of potassium sulphate, 10-20 parts of compound probiotics, 30-50 parts of epoxy resin, 5-10 parts of inorganic conditioner, 2-5 parts of plasticizer, 2-10 parts of curing agent, and 100-200 parts of water. If the fertilizer is used by the sago cycas, three years later, each sago cycas can be sold at RMB 20-25, five years later, each sago cycas can be sold at RMB 30-35, and ten years later, each sago cycas can be sold at RMB 50-55.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special fertilizer for cycads and its preparation method and application. Background technique [0002] Cycas, also known as iron tree, phoenix-tailed banana, banana, and fire-proof banana, belongs to the cycad family, and cycads are evergreen trees. Cycads are resistant to drought, avoid stagnant water, and like moist soil. In the dry season, it needs to be irrigated in time to replenish water. In the rainy season or when the planting is low-lying, attention should be paid to ditching and drainage to prevent soil water accumulation. Potted cycads should be watered when they are dry and wet, and they should be watered once every 1 to 2 days. In hot and hot seasons, the leaves can be sprayed with water regularly to keep the leaves dark green. Cycads like weak acidic environment and iron nutrition. Therefore, if 0.2% FeSO4 can be added regularly when watering, ...

Problems solved by technology

Then, in terms of cycad fertilizers, it is necessary to solve the problem of fully absorbing fertilizers. At present, cycad fertilizers generally do not have a slow-release function. In addition, the nutrients in the fertilizer are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of cycads, resulting in malnutrition in the later stage. In addition, in the process of fertilization, it is also necessary to adjust the timing of fertilization reasonably, resulting in nutrient imbalance and low fertilizer absorption and utilization, resulting in low yield of cycads
