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 preparation for foliar spraying with multiple functions, specifically a preparation for increasing chlorophyll content of crops, increasing photosynthetic rate, strengthening nutrient transformation, promoting fruit setting and swelling of fruits and vegetables, increasing yield, improving quality, and strengthening crops. Stress resistant foliar spray formulation. Background technique [0002] Fruit setting refers to the phenomenon that the young fruit 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 fruits and vegetables are too few, and the yield is also low. Factors that affect fruit setting include the variety characteristics of the fruit and vegetable, the nutritional status of the plant, the quality of the flower buds, the pollination, fertilization and external conditions during flowering.

Problems solved by technology

However, when a certain medicament is used alone, it often improves fruit setting, and produces side effects such as empty fruit, cracked fruit, and hardening of the fruit stem, which cannot meet the requirements for improving quality.

At the same time, when two or more modulators are mixed, most of them have the problem of poor effect or side effects
