Method for improving tomato quality and yield by p-chlorophenoxyacetic acid and medium trace element fertilizer

Abstract

The invention discloses a method for improving tomato quality and yield by a p-chlorophenoxyacetic acid and a medium trace element fertilizer, wherein the method for improving the quality and the yield comprises the following steps: step one, selecting a suitable variety; step two, processing seeds; step three, seeding; step four, managing; step five, fertilizing; and step six, spraying mixed solution of a fruit and flower preserved plant growth regulator of the p-chlorophenoxyacetic acid and the boron, zinc, calcium and magnesium fertilizer in a flowering phase of tomatoes, wherein the usingconcentration of the tomato fruit and flower preserved plant growth regulator of the p-chlorophenoxyacetic acid is 35 mg/L while the environment temperature is lower than 20 DEG C, and is 25 mg/L while the environment temperature is higher than 25 DEG C; and the using concentration of the boron, zinc, calcium and magnesium fertilizer is 0.1%. According to the method, the mixed solution of the p-chlorophenoxyacetic acid and the boron, zinc, calcium and magnesium fertilizer is applied in the flowering phase of the tomatoes, the inventory of the flower and the fruit is increased, the growth is accelerated, and the nutrition fertility of the tomato growth is increased. The early yield of the tomatoes is increased by 30%, and the total yield is increased by 23%. In addition, the labor force issaved, and the utilization ratio of the fertilizer is improved. The deficiency of the prior art is overcome.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for improving tomato quality and yield by adding p-chlorophenoxyacetic acid with medium and trace fertilizers. Background technique [0002] In the prior art, the tomato flower-preserving and fruit-preserving growth regulator is applied in a separate spraying manner, resulting in an increase in flower and fruit retention, accelerated growth, and insufficient supply of medium and trace elements, which affects the full improvement of tomato quality and yield. [0003] In the case of greenhouse and greenhouse cultivation, it is not conducive to the flying of insects. At the same time, the wind speed in greenhouses and greenhouses is very small, which is not conducive to tomato pollination and fruit setting. Therefore, it is necessary to use tomato flower-preserving and fruit-preserving plant growth regulator (p-chlorophenoxyacetic acid PCPA, 25-35mg / L, the applica...
