In recent years, greenhouse vegetables are very common. The advantage is that it can artificially control the time of vegetable market, which is one of the ways for growers to increase their income, and has high economic benefits. However, there are many people who have some misperceptions about greenhouse vegetables. The following small series will introduce you to some common mistakes in the greenhouse vegetable cultivation process!
First, the higher the temperature, the higher the output
Some vegetable farmers think that the greenhouse greenhouse is heat preservation, so the higher the temperature, the faster the vegetables grow. This is wrong, because each vegetable has its own optimal growth temperature, generally not exceeding 35 °C, otherwise it will strengthen its respiration. It causes physiological disorders, causing problems such as falling flowers and fruit, frequent diseases, and other serious problems.
Precaution:
According to different vegetable varieties, the growth temperature management is carried out to prevent the plants from growing at a high temperature and the reproductive growth imbalance. When the temperature is too high, it should be ventilated and cooled in time.
Second, the more fertilization, the higher the yield
Some vegetable farmers apply a large amount of fertilizer to greenhouse vegetables in order to produce more, but in fact, if the vegetables are over-fertilized, there will be reverse osmosis problems, causing the plants to dry up. Especially when the temperature of the greenhouse is high, the organic fertilizer decomposes quickly, and the amount of nitrogen volatilization is large, which is highly likely to cause ammonia poisoning.
Precaution:
Fertilizer supply is strictly carried out according to the growth of different vegetables, organic and inorganic combination, balanced fertilization, and full play of fertilizer. If ammonia poisoning occurs in the greenhouse, it should be immediately ventilated and watered, and sprayed with brassene lactone and water soluble fertilizer (note the concentration is low).
Third, the more seedlings, the higher the yield
Some vegetable farmers have a pity of seedlings, can not bear the seedlings and seedlings, just thinking that leaving more plants will be more harvest. In fact, because of the low temperature in winter, the weak light intensity and short lighting time, the photosynthesis is worse, the carbohydrate synthesis is less, and the close planting of vegetables only exacerbates the harm and cannot obtain high yield.
Precaution:
It is better to use the reasonable thinning of the overwintering vegetables to ensure that the vegetable plants are not crowded and not blocked.
Fourth, the plant is more prosperous, the higher the yield
Some vegetable farmers think that the strong growth of the plants is not a good phenomenon. In fact, it is not all because the early vines are prone to cause prolonged growth, excessive vegetative growth and reproductive effects, which may cause a decline in yield.
Precaution:
In the seedling stage seedlings, promote roots under the tie, form strong seedlings; timely germination, snoring and removal of old leaves, reduce nutrient consumption; rational use of control agents.
5. The more you spray, the higher the output.
Many vegetable farmers spray one medicine every 2-3 days in the middle and late stages of vegetable growth. It is generally believed that if the spray is sprayed diligently, it can prevent the spread of diseases and increase the yield of vegetables.
Precaution:
Cooling by lobed ventilation, improving the environment inside the shed and reducing the occurrence of diseases; paying attention to soil improvement problems caused by soil-borne bacteria, can prevent soil spray during transplanting; symptomatic spraying, preferably choose Copper and zinc-containing agents can both sterilize and enhance the ability to resist bacteria and promote crop growth.
Sixth, the more the number of turns, the higher the output
The investment in the construction of greenhouses is very large. Therefore, the vegetable farmers can't be idle, and try to use a variety of crops. Therefore, the deputy scorpion and the main scorpion, the main scorpion scorpion scorpion, and the planting squatting times are often counterproductive, resulting in low yield of greenhouse vegetables. Low efficiency.
Precaution:
Every year in the summer, stay in the deep water for a period of time to pour water, salt, sterilization, shed worms, mature soil to ensure that the soil is loose and breathable.
The above is the introduction of six common misunderstandings in greenhouse vegetable cultivation. Some growers think that the bigger the vegetables, the easier it is to sell them. In fact, if vegetables grow too large, their internal tissues will age and the variety will decline. After maturity, pick it up in time and do it in the morning.
