The first is the control of the temperature in the greenhouse. During the high temperature season, when the night temperature is too high, it is easy to cause the plants to prosper. The effective way to reduce the night temperature is to reduce the heat storage of the walls and soil during the day, such as shading, irrigation, and intercropping vegetables.
The second is moderate fertilizer control. The vegetable grower can delay the original watering time by 2 days. At the same time, pay attention to the amount of watering, drench it, and avoid flooding. In summer, the amount of evaporation is large. When the water is energetically prosperous, it is advisable to use measures such as groundwater pouring and ploughing and hoeing to avoid excessive water control and affect the normal growth of plants.
The third is timely fruit retention and reasonable pruning. Combining the growth of the plants, it is necessary to keep fruit early for prosperous plants, and to delay fruit picking, to compete for plant nutrition as much as possible, and to reduce nutrient flow to the plants. On the contrary, when the plants are weak, they must be picked early. Prosperous plants should be properly pruned late.
The fourth is to choose the appropriate control Wang pharmaceutical. Can promote the use of Kao Wang No. 3, can be assimilation of the induction of plant cell transmembrane signal conversion, forcing a large amount of nutrients back to the top of the rich, red tip inertial advantage quickly weakened to the top of the situation. The main nutrient of the main body shifts to the young fruit development system, enhances the vitality of fruit enlargement, avoids the phenomenon of leaf hypertrophy, and improves field permeability.
