Long-acting slow release fertilizer for grapes

Abstract

The invention relates to the technical field of agricultural fertilizer, and particularly relates to a long-acting slow release fertilizer for grapes. The long-acting slow release fertilizer comprises the following components in parts by mass: 32-40 parts of nitrogen, phosphorus and potassium, 25-30 parts of organic matter, 10-15 parts of calcium, magnesium and sulfur serving as secondary elements, 4-5 parts of trace element, 0.1-0.3 part of polyacrylamide, 0.01-0.03 part of a soil conditioner, 0.08-0.15 part of a fertilizer synergist, 0.01-0.03 part of a fertilizer controlled-release agent and 3-6 parts of bentonite. By adopting the long-acting slow release fertilizer for grapes provided by the invention, the effective time of the fertilizer is long, the yield and the quality of the grapes are greatly improved, the pulp is delicious, the nutrition is abundant, soil hardening is avoided, the grape plant grows vigorously, and the disease and insect resistance is strong.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a long-acting slow-release fertilizer for grapes. Background technique [0002] Grape, also known as grape, is a fresh fruit with delicious taste, easy eating and high nutritional value. It can also be processed into grape juice, raisins and wine with high nutritional value. Grapes need to absorb more nutrients in a growth cycle. Not only do ordinary fertilizers provide more nitrogen, phosphorus, and potassium. According to the theory of wooden barrels, if they lack other nutrients, they will not be able to grow normally, and the plants will be thin and small.

Problems solved by technology

Grapes need to absorb more nutrients in a growth cycle. Not only do ordinary fertilizers provide more nitrogen, phosphorus, and potassium. According to the theory of wooden barrels, if they lack other nutrients, they will not be able to grow normally, and the plants will be thin and small. Qi, low pollination rate, seriously affecting yield

[0003] At present, in the process of grape cultivation, on the one hand, chemical fertilizers are excessively used, and on the other hand, the nutrients used in chemical fertilizers are not comprehensive, which leads to insufficient accumulation of dry matter and breaks the balance point of grape growth. Although the grape yield is high, the carbon and nitrogen metabolism is not coordinated. Difficulty in grape fruiting and coloring, which affects the absorption of nutrients by grapes

There are also organic fertilizers. Although organic fertilizers have long fertilizer effects, their nutrient content is low and cannot fully meet the needs of high yields.

At present, the method to solve these problems in fertilization is first to increase the amount of organic fertilizer, and second is to use a small amount of chemical fertilizer for multiple times. With the continuous expansion of grape planting, organic fertilizer can no longer meet the needs, and repeated application of chemical fertilizer increases labor. cost and effort
