Water-retaining fertilizer for grapevine and preparation method thereof

Abstract

The invention discloses a water-retaining fertilizer for grapevine and a preparation method thereof. The water-retaining fertilizer comprises the following raw materials by weight: 35 to 50 parts of calcium magnesium phosphate fertilizer, 20 to 25 parts of rice husk powder, 5 to 10 parts of tea shell powder, 2 to 4 parts of iron ore, 4 to 6 parts of vermiculite powder, 2 to 4 parts of bamboo vinegar liquid, 5 to 7 parts of corn flour, 3 to 4 parts of composite probiotics, 2 to 4 parts of sulfamic acid, 0.5 to 0.7 part of copper sulfate, 0.2 to 0.4 part of boric acid, 0.5 to 0.7 part of zinc sulfate heptahydrate, 2 to 3 parts of potassium sodium tartrate, 2 to 3 parts of a wilfordine preparation, 8 to 10 parts of a soil water-retaining agent and 2 to 4 parts of chlorothalonil. The water-retaining fertilizer provided by the invention has multiple effects like water retention effect, fertilizer retention effect, soil improvement effect and substantial yield increase effect and effectively improves the granular structure of soil, so the utilization rate of the fertilizer is improved, water retention capability of soil is enhanced, soil structure is improved, growth of the grapevine is promoted, and grape quality is improved.

Description

technical field [0001] The invention relates to a vine water-retaining fertilizer and a preparation method thereof, belonging to the technical field of fertilizer processing. Background technique [0002] China's table grape industry is developing rapidly and the planting area is increasing continuously. However, there are many problems in China's table grape production. Among them, in the process of grape planting, on the one hand, excessive use of chemical fertilizers prevents the nutrients from being fully absorbed. On the one hand, the nutrients used in the chemical fertilizers are not comprehensive enough, so that the accumulation of dry matter is not enough, so it is far from meeting the nutritional needs of the grapes, so the growth of the vines is slow, and the grapes produced are small, light in weight, and poor in disease resistance; Leaf spot disease and high fruit drop rate. With the continuous increase of grape planting, it is imminent to solve the problem of fe...
