Special fertilizer for facility vegetable field fruit and vegetable and preparation method

Abstract

The invention discloses a special fertilizer for facility vegetable field fruit vegetable and a preparation method, belonging to the technical field of fertilizer and manufacturing methods. The special fertilizer for the facility vegetable field fruit vegetable comprises the following compositions in parts by weight: 18-22 parts of N, 23-27 parts of K2O, 4.0-5.0 parts of MgO, and 0.3-0.4 part of B; the special fertilizer can effectively prevent the problem that potassium in the facility vegetable field is massively accumulated to cause the antagonism of potassium ions to magnesium ions and further cause the fruit and vegetable in the facility field to lack magnesium. The invention simultaneously provides the preparation method and an application method of the special fertilizer, the preparation method is easy to obtain raw materials, simple for procedures, and easy to operate; and the application method is controlled according to specific growth conditions of different fruits and vegetables, is simple and easy and has good effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers and preparation methods thereof, and in particular relates to a special fertilizer for fruits and vegetables in a facility vegetable field and a production method. Background technique [0002] Facility cultivation is a method that can artificially create a microclimate suitable for the growth and development of horticultural crops by using facilities and equipment such as heat preservation, cold protection or cooling, and rain protection in seasons that are not suitable for crop growth and development, so that it is less or not affected by natural seasons. Cross-seasonal planting patterns for horticultural crop production. [0003] Vegetable protected cultivation, as an effective way to increase vegetable yield, has developed rapidly in our country. The cultivated area of ​​protected vegetables in my country increased from less than 7,000 hectares in 1980 to 3.347 million hectares in 2008, a...

AI Technical Summary

Problems solved by technology

However, with the increase of planting years in the facility vegetable field, a large amount of phosphorus and potassium accumulate in the soil, the supply capacity of phosphorus and potassium is very high, the ratio of potassium to magnesium is too high, and the antagonism of potassium and magnesium causes magnesium deficiency symptoms in fruit and vegetables
