Greenhouse tomato cultivation management technology

Greenhouse tomatoes are nursed in sheds and distributed in sheds. The temperature is easily controlled. As long as good varieties are selected and management is appropriate, high yield, high yield and high yield can be achieved. Its main cultivation techniques are:

Level the field. When selecting the land, care should be taken to carry out more than two years of rotation with non-solanum and cruciferous vegetables to clean the pastoral areas, especially to remove the diseased fruits from the fields and burn them or bury them deeply, and spray the general tree to disinfect, sterilize and prevent infections. Antibacterial community transmission. According to local conditions, the shed must be repaired and repaired. The shed should be sturdy and durable, with strong wind resistance and thermal insulation. The land should be deep-turned, the top-dressing fertilizer should be applied to the bottom, and the rational allocation of various essential elements and fertilizers should be paid attention to. The lyrical condition should be suitable, ventilation and drainage should be convenient, and the water should be confined.

Seed treatment. After the seed is selected, soak in the warm soup and slowly pour it into the pot with 60°C hot water (three open and one cool) and stir it in one direction. The amount of water should be 2 to 3 times that of submerged seeds. When the water temperature drops to 35°C, stop stirring, and soak in warm water of 35-25°C for 5-6 hours. Then remove the seeds and place them in an environment of 25-30°C to germinate (every day rinse with the corresponding temperature of warm water 1～2 Secondly, after 2 to 3 days, half of the seed “show white”, use a new high-fat membrane seed dressing, can repel underground pests, isolate virus infection, does not affect germination and swelling function, strengthen respiratory intensity, and increase seed germination rate .

Timely sowing. Seeds that have sprouted buds are sown on pre-prepared seedbeds. Seed soil shall be sieved through sterile soil and fully smashed and troshed. The trotters shall be sifted and sieved. After the whole subterranean species is covered, 0.8 cm of wet soil shall be covered, covered with plastic film, and a small shed shall be erected. With the spraying of 600-800 times the new high-fat film, it can protect the water evaporation, sun protection, drought, insulation, antifreeze, anti-soil compaction, isolation of pests and sources of suffocation and eliminate, increase seed emergence rate.

Seedling protection. The use of new high fat film sprayed on the plant surface during the seedling period of tomatoes can prevent the infection of pathogens, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and protect seedlings.

Control the tip to promote flowers. The tomato in the greenhouse is generally single-stalked and pruned, leaving only one main stalk, and all side branches are completely removed. The side branch should be selected for sunny morning. With the promotion of spraying, Huawang No. 3 suppresses the main tip and grows, forcing the tip of the elite nutrition to flow back, without the need for artificial summit buds, instead of hormone killing, transforming growth nutrition into reproductive nutrition, promoting flower bud differentiation, and improving the quality of pollen fertilization.

Rational fertilization. Greenhouse tomatoes enter the fruiting period. With the temperature rising, the growth rate of the plants is accelerated and the growth volume is increased. At this time, attention must be paid to the start of reasonable flushing of nitrogenous fertilizer to ensure the nutrient supply of tomatoes. The topdressing of trace fertilizers and the root-applying capsules with root can induce the absorption, digestion and release of nitrogen, phosphorus, potassium and various trace elements in the soil, increase the positive energy of fruit development, and optimize the fruit quality.

Clever prevention of bud blight. After the occurrence of bud blight, care should be taken to cultivate new fruit spikes, remove some leggy shoots, and spray a new high-fat film to form a protective film to prevent the invasion of pathogens; at the same time, leave an inflorescence with a better growing head in place and use it. Replace lost ears to reduce yield loss.

Keep flowers strong. During the fruiting period of greenhouse tomato blossoming, Zhuang Tiling enhances the quality of pollen fertilization, enhances fruit cycle rate, promotes fruit development, has no abnormalities, no shells, no grains, good uniformity, high quality, and high yield of vegetables and fruits. .

Vitamins Powder

Ascorbic acid (vitamin C) is an essential vitamin that is well known for its effects on the immune system. L ascorbic acid bulk vitamin C powder is naturally sour and is commonly used in candy to add a sour taste. When it is ingested, it goes to work circulating through all of the watery areas of the human body (once it has been absorbed into the intestines, of course). From there, ascorbic acid may help in the fortification of collagen while acting as an antioxidant during the trip. It may also assist in the repair of damaged tissue and in helping to maintain healthy levels of collagen in already healthy individuals. Vitamin C also has a host of other general uses.L-ascorbic acid bulk vitamin C powder is a colorless crystal, odourless, acidic taste. Soluble in water and ethanol. Stable in dry air , and its solution is not stable. As well as, L-ascorbic acid bulk vitamin C powder takes part in many metabolism procedures in the human body, helps decrease brittleness of blood capillaries and increase body resistance
