Winter greenhouse shed tomato, wax gourd, garlic sprouts, garland chrysanthemum three-dimensional cultivation, can use the greenhouse to produce anti-season vegetables for an annual anniversary, the benefit is very considerable.

Tomato selection of good varieties: should choose early Feng, Xifen No. 3, L402 and other varieties. Cultivate strong seedlings: At the end of October or early November, tomato seeds are soaked in 10% phosphoric acid three-nano solution for 20 minutes, washed out, and placed under a temperature of 25° C. for germination. When most of the seeds are exposed to the radicle, they can be sowed. After the seedlings are unearthed, the daytime temperature is controlled at 22--25°C and 13--14°C at night. When the seedlings grow to 2 leaves and 1 heart, they are divided into seedlings with nutrients. Do not water before splitting. Site preparation: At the end of December, ridges were set at a 60-cm line spacing, 20-cm ridge height and 30-cm width at the bottom of the ridge. In combination with site preparation, 10,000 kg of organic fertilizer and 50 kg of diammonium phosphate are applied every 1/15 hectare (1 mu). In mid-January of the following year, it was selected at noon on a sunny day, and planted seedlings were planted on a ridge at a spacing of 25 cm. Management after planting: During the seedling period, the temperature is kept at 25--30°C during the day and 15-18°C at night. During the result period, the temperature was kept at 23--28°C during the day and 15-17°C at night, and after the weather became warmer, the temperature exceeded 28°C. Fertilizer water management: appropriate watering of the seedling period. After the first spike is sitting, it is combined with watering, and 15 kg of diammonium phosphate is applied per 1/15 hectare. Afterwards, each sitting fruit is watered and topdressed once, and each time 1/15 hectares is applied 10-75 kg of compound fertilizer. Plant adjustment: After easing the seedlings, condolences, vines, and pruning are performed. Paulownia fruit: can be sprayed with a tomato spirit solution with a concentration of 20--30 mg/kg or with a concentration of 15-2 mg/kg 2,4-D.

Winter melon seedlings: selection of Guangdong Qingpi melon, in early March seedlings. The seeds were soaked in warm water at 30°C for 7--8 hours and then at 25--30°C for moisturizing and then germinating. After emergence, the daytime temperature is maintained at 23--26°C and 15°C at night. At the end of March, the water was cut into pieces for hardening. Colonization: In early April, the winter melon seedlings with soil ridges were planted in the middle of the south side of the shed with the spacing of 60 cm. Management: The gourd enters the dumping period and can be applied with compound fertilizer, 15 kg per 1/15 hectares. Before the opening of the female flowers, watering was controlled, and then the compound fertilizer was applied after sitting on the melons. 10 kg were used for every 1/15 hectares. Melon is dominated by the main vine, generally leaving 1-2 melons per plant, leaving the second and third melons. After sitting on the melon, leave 5--7 leaves topping.

The garlic, tomato and wax gourd were harvested in early July. At this time, they should promptly exterminate the soil and make a 50-cm-wide flat rake. Combining land preparation, 1,000 kg of organic fertilizer, 25 kg of urea, and 50 kg of phosphate fertilizer are applied every 1/15 hectares. Jinxiang white garlic was selected and soaked in gibberellic acid at a concentration of 1 mg/kg for 12-24 hours. After soaking the garlic, remove and release for 1–2 days, dig out the stem plate with a knife and keep the flap open. Planting and management: In the middle and late July, the whole head of garlic was planted in the flat pods, and the garlic gap was filled with loose garlic cloves. The garlic seeds were covered with 3--5 cm thick sand. After the emergence of greenhouses in the greenhouse to take the shade to cool, and often water cooling, with water fertilization, garlic harvest 2 茬, you can spray a concentration of 15-30 mg / kg of gibberellin solution to promote growth, the end of October harvest.

Artemisia halodendron seeds were sown in garlic sprouts in early November. Before sowing, the seeds are first soaked in cold water for 24-36 hours, and then germinated at 16--20°C. After 5-6 days, 80% of the seeds are ready to be sown. One week after sowing, seedlings can emerge. When the seedling height is 5--6 cm, top dressing and watering. When the seedling height is 9-12 cm, the second fertilizer will be traced. Each time, 1/15 hectares of ammonium bicarbonate will be topped with 15-20 kg of ammonium bicarbonate. When the height of seedlings is more than 15 cm, fertilizer and water should be properly controlled. The daytime temperature during the growth period is controlled at 17--22°C and 8-10°C at night. Plants grow to about 25 cm for proper harvesting. The harvest can be completed by the end of December to the beginning of January of the following year. At this time, tomatoes, cucumbers and other vegetables can be transplanted.

Pheromone

Insect pheromones are compounds used by insects to represent various information such as aggregation, foraging, mating, and alerting. They are the chemical molecular language of insect communication. At present, the basic control measures for pests in agricultural production mainly rely on chemical pesticides, but the long-term uncontrolled use of chemical pesticides has brought many side effects. The first is the emergence of pest resistance, which causes the use of drugs and drug concentrations to increase, the cost increases year by year, and the prevention and control of increasingly difficult; the second is to disrupt the ecological balance, while controlling a large number of natural enemies were killed, causing the pupae of secondary pests; Third, it pollutes the environment. A large amount of pesticides remain in crops, soils, rivers, lakes, and seas, and they are enriched in the human body through the form of food chain, causing another harm to humanity. Therefore, relevant research departments in many countries are currently working hard to explore and study new approaches and technologies for pest control. These studies include: the development of new, efficient, environmentally friendly, low-toxic, low-residue chemical pesticides; natural enemy insects and microorganisms The use of pesticides; insect sterilization technology and the application of insect hormones; among them, the research on the use of insect hormones, especially insect sex pheromones for pest control, is receiving increasing attention and attention.

Research on insect pheromone has been developing rapidly. Since the first insect pheromone Bombykol, has been isolated and identified, more than 2,000 insect pheromones and their analogs have been identified and synthesized worldwide, of which more than 100 insect pheromone To achieve commercial production, the production and research of Lepidoptera sex pheromones is the most extensive and comprehensive.
