Foliage spraying preparation for promoting fruit setting and fruit swelling and enhancing crop stress resistance

Abstract

The invention discloses a foliage spraying preparation for promoting fruit setting and fruit swelling and enhancing crop stress resistance. The preparation comprises the ingredients including fulvic acid, DA-6, 2,4-D sodium salt, alpha-pimacol, gibberellin, zeatin, dimethyl sulfoxide, butylcellosolve, sodium tetraborate, zinc sulfate, ferrous sulfate, molybdenum sulfate and magnesium sulfate. After the preparation is sprayed, nutrient substances are rapidly transferred from blade surfaces and are gathered at the plant reproduction active part, and the center endogenous hormones level of fruits is improved; the cell division is promoted, the cell size is amplified, the fruit swelling is accelerated, the chloroplast development and the chlorophyll formation are promoted, the photosynthetic efficiency of leaves is improved, and the unit area yield is increased; the flowing of nutrient substances to female flowers is enhanced, the fruit development speed is accelerated, the uniform fruit development is controlled, the deformity is reduced, the fruit surface is kept fresh, bright and smooth, and the commodity rate is obviously improved; and the immunological competence of plants are excited, the resistance is improved, the occurrence of the pest and disease damage is reduced, the senescence is delayed, and the picking period and the fruit shelf period are prolonged.

Description

Technical field

[0001] The invention relates to a foliar spray application formulation with multiple functions, in particular to an increase in crop chlorophyll content, increase photosynthesis rate, strengthen nutrient transformation, promote fruit setting and expansion of fruits and vegetables, increase yield, improve quality, and enhance crops Resistant foliar spray formulations. Background technique

[0002] Fruit setting refers to the phenomenon that young fruits formed by pollination and fertilization can grow and develop normally without falling off. Fruit setting is a prerequisite for yield. The fruit setting rate is too low, the fruit and vegetable are too little, and the yield is low. Factors affecting fruit setting include the characteristics of fruit and vegetable varieties, plant nutritional status, flower bud quality, pollination during flowering, fertilization and external conditions. Measures to increase the fruit setting rate include: ①Improve the quality of f...
