Prevention of empty fruit measures for tomatoes
The following measures are taken to control the empty fruit of tomatoes: 1, choose a variety of ventricular chambers. 2, do a good job of light temperature control, create a good light temperature conditions for fruit development. When the nursery period meets cloudy low light, the temperature should be appropriately increased during the day and the temperature should be controlled at about 17°C during the night. Before and after flower buds of the first flowering buds are differentiated, the temperature should be controlled to avoid the occurrence of low temperatures below 10°C. The flowering period should be avoided. High temperature above 35°C harms fertilization and promotes normal development of the placenta. 3, the rational use of plant growth regulators. In the flowering period, pollen fertilization and other methods are used to promote the quality of pollen fertilization. Spraying 15-20ppm of rhein-repellent fertilizer can also prevent fruit drop and promote fruit enlargement. 4, strengthen fertilizer and water management. The use of formula fertilization technology, the rational allocation of nitrogen, phosphorus and potassium, adjust the ratio of root to shoot, to avoid excessive foliage, so that the plant vegetative and reproductive growth coordinated and balanced development.
The Expandable Circuit is non-rigid tube used to convey gases or vapors between components of a breathing system.
