After the greenhouse vegetables are planted, it is an important period for the management of greenhouse vegetable seedlings. Often this time, the vegetable seedlings are prone to problems of one kind or another. For example, if they are planted too early, the greenhouse vegetables fall into a bad growth environment; the greenhouse vegetables are prosperous and grow unevenly; Many soil-borne diseases affect the growth of greenhouse vegetables. It is difficult for vegetable farmers to solve these problems in accordance with conventional management methods. Therefore, it is necessary to combine the actual situation and change the detailed management to lay a good growth foundation for the growth of shed vegetables. The planting time is advanced, and the management details should be At present, many vegetable farmers have advanced the planting time of vegetables in order to get a good market. However, the autumn vegetables planted in advance have fallen into a bad growth environment, which has caused many problems in the shed. The high temperature in the early stage of root cultivation is detrimental to the normal development of the root system of the greenhouse vegetables. Appropriate use of rooting agents to assist rooting can promote the rapid growth of the greenhouse vegetables. After entering the flowering and fruit setting period, two points should be paid attention to when watering and fertilizing: one is to pay attention to the amount of watering not too large, so as not to cause the soil to be too dry and wet; the second is to insist on using rooting agents. When choosing rooting agents, non-hormonal rooting agents such as chitin, amino acids and alginic acid can be used. In addition to the use of rooting agents, the application of biological fertilizers is also beneficial to the growth of roots. Timely replenishment of boron and high temperature can easily cause the absorption of boron fertilizer to be hindered, and boron fertilizer is directly related to the quality of flowers. Therefore, it is necessary to pay attention to supplementing boron fertilizer on the leaf surface before and after the flowering of shed vegetables. 600 times solution of borax can be sprayed. When using drugs rationally, care must be taken not to use them indiscriminately. There are strict requirements on what medicine to use, how much medicine to use, and when to use it. After the shed vegetables enter the flowering period, they use medicine to dip the flowers. Some people use a concentration of medicine to treat the flowers regardless of the temperature, noon or morning. This will inevitably affect the development of the fruit, and it is easy to appear deformed or unable to hold the fruit. Therefore, the concentration of anthers should be adjusted in time according to the temperature. After the temperature drops, the method to control the prosperity Physical control can effectively regulate the growth of vegetables with poorer growth. From the management perspective, one is to reduce the frequency of watering, and to increase the air outlet to lower the night temperature; the second is to tilt the plant to weaken the top advantage, such as tomatoes; the third is to increase fruit retention Fruit picking should be delayed appropriately; fourth, rational pruning and branching, and proper retention of some side branches and deformed fruits that consume plant nutrients can play a certain role in controlling prosperity. The use of regulators for balanced growth is well known. Some regulators currently on the market have a two-way regulation effect. You only need to pay attention to the dosage when using them to achieve the purpose of regulating plant growth. If Ai Duoshou (compound sodium nitrophenolate) is 3000 times, cytokinin 600 times, seaweed products 500~600 times, amino acid foliar fertilizers such as photosynthetic power 300 times, conventional potassium dihydrogen phosphate 300 times, all can achieve The purpose of balancing growth and controlling prosperity. The use of prosperous control agents requires vegetable farmers to select the appropriate prosperous control agents and concentration in combination with plant growth to avoid excessive prosperous control. Commonly used agents for controlling proliferation include chlormequat, mepiquat, chlorophyll, paclobutrazol and so on. When spraying, you should also pay attention to the weather conditions, avoid rainy weather after the application, and avoid phytotoxicity or excessive control. In addition, spraying some azole agents can also play a certain role in inhibiting growth. There are many soil-borne diseases, and the way of fertilization should be Before planting vegetables, apply bio-organic fertilizer, pure organic fertilizer, or microbial inoculants containing beneficial bacteria such as Bacillus and Trichoderma, such as smart brand functional organic fertilizer (containing compound chitin), Zhongnong Green Kangkang replanting microecological preparations can not only supplement soil organic matter, facilitate the formation of humus, and promote the formation of soil aggregate structure; but also can cultivate beneficial soil flora and inhibit soil-borne pathogens and nematodes. On the one hand, the application of microbial inoculants and bio-organic fertilizer in holes can prevent soil-borne diseases such as root rot, fusarium wilt, root knot nematodes from infecting roots; on the other hand, it can create a suitable soil environment for the root system in advance. Conducive to the rapid adaptation of the root system to the soil, in simple terms it is disease prevention and root promotion. For example, the application of microbial agents containing Paecilomyces lilacinus or Actinomycetes, or application of antibacterial 968 strong seedlings or Yuyuan Miaokang, mixed with soil and colonization can inhibit root-knot nematodes to a large extent , And promote rooting and slow seedling. Root irrigation usually prevents soil-borne diseases. Vegetable farmers are used to irrigating roots with chemicals. It is undeniable that irrigating roots with chemicals is effective, but while it kills harmful bacteria, it also kills beneficial bacteria in the soil. Therefore, vegetable farmers should develop the habit of re-irrigating rooting agents after irrigating the roots with medicament, and replenishing the number of soil microorganisms in time to ensure that beneficial bacteria always "occupies" the dominant position, such as Baixingfu Bar and Runke Biological Bacteria Herbalife and others. During the vegetable growth period, the continuous application of microbial agents such as Bacillus, Trichoderma, etc., which contain disease-preventing and growth-promoting effects, can proliferate and transfer microorganisms in the rhizosphere and plant bodies of the vegetables to give full play to the "regulation" function of the microorganisms. The purpose of preventing soil-borne diseases and improving soil. Disclaimer: Some articles on this website are transferred from the Internet.
