Since May, the temperature in many areas has been increasing, and the situation of “heat, heat and heat†has gradually emerged throughout the country. With the increase of temperature, the convenience of vegetable management will also be a special need. Where the attention is more difficult to manage, how can the high yield of vegetables be achieved during the high temperature period? Several standardization measures are shared with everyone.
1. Focus on curing blades
During high temperature, the leaf transpiration is large, the photosynthetic rate is faster, and the load is heavier. Therefore, the leaves should be maintained continuously to ensure the best photosynthesis, and the rejuvenating agent should be sprayed once every 7-10 days to improve the resistance of the leaves and the whole plant. The force has a significant effect. Adjust the dosage according to the growth of the plant. Before the flowering, each sprayer (15kg) should be mixed with 200ml of the rejuvenating agent. The result period is 350-500ml per sprayer, and continuous spraying should be adhered to.
2. Reasonable regulation and growth
The main problem facing the high temperature period is that it is long, so it must be properly regulated.
3. Do a good job of shading and cooling
The best choice for shading is the shading net, because the shading net can be adjusted manually. Some spray mud or ink on the film, which will reduce the light transmittance to a certain extent, which will lead to crop length. The sunshade net should not be covered all day or several days in a row, covered at about 9:30 in the morning, and closed at around 4:30 in the afternoon.
4. Use watering to lower the ground temperature
If the ground temperature is too high, it will cause damage to the roots of the crops, resulting in poor growth of the crops. When the ground temperature is too high, the water is cooled by the small water poured in the water, and the watering in the high temperature period is preferably selected in the evening.
5. More need for rooting in the high temperature period
Everyone knows that the roots of the crops must be cured in the winter, but in the high temperature period, the rooting management cannot be relaxed, because in the case of too high ground temperature, many capillary roots will burn or die, so it is necessary to maintain the root system continuously to ensure high yield.
These are some of the main points of high-temperature vegetable management. Do you think it makes sense? Summer is coming, everyone must pay more attention to prevent pests and diseases.
