[0033] Preparation of Controlled-release Compound Fertilizer for Cucumber Seedlings

[0034] 1) Determination of the release period and components of cucumber seedling controlled-release compound fertilizer

[0035] According to the growth characteristics of transplanted cucumbers, the seedling stage is 3-4 weeks, and after transplanting, the seedlings are slowed down to about 3 weeks in the early stage of field growth (the beginning of flowering), and the release period of the controlled-release urea is determined to be 40-50 days;

[0036] Through the test of different dosages of phosphorus ammonium nitrate, to promote root growth, the minimum dosage for forming robust seedlings determines the dosage of phosphorus ammonium nitrate;

[0037] Through experiments of different dosages of controlled-release nitrogen, the dosage of controlled-release urea was determined by the maximum safe dosage of controlled-release nitrogen and the minimum dosage of ammonium nitrate phosphorus to...

Abstract

The invention discloses a cucumber seedling growing controlled-release compound fertilizer and a method for preparing the same. The cucumber seedling growing controlled-release compound fertilizer comprises, by weight, 10-12 parts of coated urea, 2-4 parts of ammonium phosphor nitrate, 3-4 parts of phosphorus fertilizers and 3 parts of potassium fertilizers. The coated urea comprises urea and coating materials and comprises, by weight, 44% of N, the initial dissolution rate of the coated urea is larger than 0 and is smaller than 2%, and the nutrient release period of the coated urea is 40-50 days; the ammonium phosphor nitrate comprises, by weight, 30%-32% of N and 4%-6% of P2O5. The cucumber seedling growing controlled-release compound fertilizer and the method have the advantages that the coated controlled-release urea is a nitrogen supply body, appropriate quantities of ammonium phosphor nitrate, phosphorus fertilizers and potassium fertilizers are added into the coated controlled-release urea, accordingly, nutrient supply can be synchronized with the nutrient requirements in cucumber seedling growing periods, growth and development of the root systems of cucumber seedlings canbe stimulated, controlled-release nitrogen which is not released during transplanting can be reserved at rhizospheres, the nutrient requirements of the root systems of transplanted plants can be met,and the purposes of reviving the seedlings in advance and promoting growth of plants can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a controlled-release compound fertilizer for cucumber seedling cultivation and a preparation method thereof. Background technique [0002] Cucumber is an important vegetable crop and occupies an important position in vegetable cultivation in my country. Cucumber cultivation in my country has the characteristics of large cultivation area, various forms and high total yield. Seedling transplanting is widely used in cucumber production in my country due to its advantages of making full use of the growing season, advancing the growth process, and densely planting all seedlings. In the production system of cucumber seedling cultivation and transplanting, the growth of cucumber seedlings is weak before transplanting, the root system is poorly developed, and the plants are not strong; the root system is seriously damaged during transplanting, and the plants ha...
