In the hot weather in recent days, the vegetables in the greenhouse have dried leaves and some blades are rolled up. What is the matter?
Liu Chunxiang, a vegetable expert from Shouguang City Bureau of Agriculture, said: “Under continuous high temperatures, the impact on vegetables can not be ignored. This period is not only easy to cause vegetable burns, but some plants will be too fast due to water evaporation, the leaves will appear The phenomenon of scrolling, especially if the leaves of vegetables such as tomatoes appear to be rolled up, and if there is a serious loss of water from the leaves, there will be a dry edge phenomenon. Once these occur, the normal growth of vegetables will be affected.â€
In this case, Liu Chunxiang suggested that the vegetables be cooled in time. "You can cool down by shading the net and shading it for at least three to five hours a day. Another one is to spray clean water in the shed around 8 am or 5 pm. In addition, spray cooling on the membrane. The agent is also a good choice, and the cooling agent can generally reduce the temperature by 45 degrees or even 6 degrees."
In addition, Liu Chunxiang particularly stressed that at noon time, we must reduce agricultural operations.
In addition to the cooling measures, Liu Chunxiang reminded farmers to supplement the vegetables with some foliar fertilizers during this time. Such fertilizers as calcium supplements and potassium supplements can increase crop resistance to adverse environmental conditions. Phosphate Potassium Phosphate Fertilizer from Tianji, because of its unique production process, is also rich in trace elements and rare earth nitrates, which is of great help in improving the resistance of crops. It may be used as a foliar spray to prevent and control, and it can also reduce The occurrence of these phenomena. â€
Liu Chunxiang particularly pointed out that in high-temperature climates, it is also a booming period for pests and diseases. She reminded farmers that when spraying drugs, they must avoid the high temperature stage from 10am to 3pm. If the spraying is likely to cause burns on the young part of the leaves, this will have a great impact on the growth of vegetables in later stages. . In addition, during summer heat, farmers must pay attention to their own protection when spraying, so as to avoid drug poisoning. After the drug is sprayed, it is best to shower in time. Be sure to develop self-protection habits and ensure safe production.
Summer watermelon cracks melon phenomenon, how to prevent?
Liu Chunxiang said: "After pollination of watermelons is completed, appropriate watering and fertilizing, but before the melon can not be stabilized before the big water can not be applied fertilizer, can wait for melons to stabilize after the appropriate pouring water, charge high potassium fertilizer. Attention must not be too large, can be appropriately increased in the second watering.When fertilizing, you can choose the ridge potassium phosphate fertilizer, as to how much the amount of rushing, generally according to the condition of watermelon growth, fertilization In addition, in order to ensure the sugar content of watermelons, some fertilizers such as potassium and calcium may be sprayed on the leaves, and these fertilizers have certain benefits for the accumulation of sugar content. Too much high-nitrogen fertilizer is applied. In addition, avoid watering at high temperatures at noon to prevent the occurrence of cracking melons."
Liu Chunxiang said: At present, we must pay attention to balanced fertilization when crops such as greenhouses or watermelons are used. In particular, we must appropriately increase the amount of organic fertilizers. When applying basic fertilizers to crops, it is best to use moderate amounts of trace element fertilizers. Like the R & F calcium silicon and potassium fertilizers on the market, the trace element fertilizer contained in such fertilizers can improve the disease resistance of crops and improve the quality of crops. In particular, calcium in fertilizers can effectively prevent the occurrence of cracked melons.
