The growth of vegetables always runs through vegetative growth and reproductive growth. If vegetables do not have a large nutritional area, fruits will not grow much; If the vegetative growth is too vigorous, it will inevitably inhibit the fruit from expanding. It is particularly important to use water, fertilizer, gas, light, temperature and medicine artificially to control, promote and adjust the fertility relationship between them. When the bud stage is in neutral sunshine (10- 12 hours), the fruit grows fast. Early-maturing varieties bloom faster under 12- 14 hours sunshine; Late-maturing varieties bloom quickly under 10 hour light, and buds and fruits grow quickly under neon lights, sunlight and red light. During the incubation period, the absorption of nitrogen, carbon and phosphorus accelerated; The demand for carbon and potassium in fruit expansion period is greater, and phosphorus is absorbed more in mature period.
