Tomato (tomato) empty fruit refers to the empty fruit between the peel and the pulp. Although the impact of tomato empty fruit on the yield is not too great, but it will seriously affect the commercial nature, reduce economic efficiency, can not but pay attention to the production. Tomato empty fruit is a physiological disease, and the number of ventricular chambers is easy to occur. Generally premature varieties have a small number of ventricles. There are many reasons for the formation of tomato empty fruit, such as spraying hormones inappropriate time, two days before flowering to flower buds, pedicels, buds sprayed on the hormone, the fruit development speed faster than the normal pollination, and promote maturation, but the placenta is more developed Defects cause ovary to produce voids; or lack of light, photosynthetic products decrease, supply of nutrients to the fruit falls short of demand, followed by the formation of voids; or weak terrain, large quantities of large quantities of bar, large amounts of nutrients that cannot be kept in the late stages of growth, carbohydrates Accumulation is small, and there are also empty fruits; or insufficient watering at the end of the result; or leaving too much fruit, the supply of nutrients is not enough to form a hollow. Control the tomato empty fruit can choose more varieties of ventricle; rational use of regulators, each inflorescence has 2/3 flowers open, spray hormones, anti-falling substance concentration of 15ppm-25ppm, do not repeat; apply base fertilizer, use Formula fertilization technology, reasonable distribution of nitrogen, phosphorus, potassium; the results of the peak period, timely recovery of fertilizer, enough water to meet the nutrition needs of tomatoes, and according to the characteristics of species, timely picking tips, so that the plant vegetative and reproductive growth balanced development.
