1. Construction of optimized facility greenhouse technology uses a plastic greenhouse without columns, a steel tube with a diameter of 2.2 cm, a width of 6.0 meters and a height of 3.0 meters. This greenhouse is strong in light transmittance, strong and durable, strong in wind resistance, and convenient for mechanized operation.
2. Annual high-efficiency stubble configuration mode Facilities The annual high-efficiency stubble configuration technology includes three seasons per year and two seasons per year. Cultivation techniques such as prevention and control, integration of water and fertilizer, clarify the reasonable stubble period and key technical points, and improve comprehensive benefits. Focus on promoting the excellent varieties such as Yunong cowpea, Lvling No. 3 hu Zi, Su Jiao No. 5 pepper, Jinyan series cucumber, Zhongnong No. 8 tomato, strawberry red cheek, Su Ke Nuo series waxy corn, 8424 watermelon. The annual planting model with high economic benefits of vegetable greenhouse cultivation includes: cabbage, tomato, cucumber three seasons a year, kidney bean (cowpea, watermelon), tomato (cucumber), pakchoi (coriander) three seasons a year, cucumber (watermelon), tomato Two seasons a year, etc., to promote intensive and efficient production of facility vegetables.
1. Cabbage, tomato, cucumber planting mode in three seasons a year (1) Cabbage. The cabbage seedlings were raised in the nutrition bowl at the end of October and transplanted in mid-November. Reserve a certain amount of open space in the shed for tomato seedling beds and fake planting land; in the middle and late January of the following year, grow tomato seedlings in the shed. When the seedlings grow to about 10 cm high, fake planting at 15 cm intervals. (2) Tomato. From late March to early April, harvest the cabbage when the false seedlings are as high as 18 to 20 cm, and then plant the tomato seedlings with soil in the cabbage planting hole. After pouring enough water to fix the roots, you can seal the membrane mouth; choose a shorter growth period Mid-mature varieties with self-sealing top, early harvest period and next cucumber planting time. (3) Cucumber. From late July to early August, at the end of tomato harvest, cucumber seedlings were cultivated in a nutrient bowl. The varieties can be Zhongnong 8 or Jinza series suitable for greenhouse cultivation. When cucumber seedlings are planted for about 15 days, remove the tomato support, plants and litter, replant the soil, fertilize, ridge, cover the film according to the method of planting cabbage, and plant the cucumber seedlings according to the row spacing of 35 cm × 40 cm, from the end of October to The harvest ended in early November.
2. Kidney bean (cowpea, watermelon), tomato (cucumber), Chinese cabbage (coriander) planting mode of three seasons a year. Sowing bean in the middle and late January, the planting method is the same as that of Chinese cabbage. Membrane direct seeding, sowing 3 to 4 seeds per hole and leaving 2 to 3 seedlings; from late May to early June, 30 to 40 days before the harvest of kidney bean Cucumbers are raised about 15 days before the harvest of kidney beans. The planting operation of tomatoes or cucumbers in the second season is the same as the first model. After the tomato or cucumber harvest is completed in the first half of November, a season of cabbage or coriander will be broadcast live.
3. Cucumber (watermelon) and tomato planting mode of two seasons a year Cucumber seedlings are bred from the end of January to the beginning of February, and the seedlings are transplanted with plastic film covering the middle and early March. From the end of May to the beginning of June, tomato seedlings are cultivated 30 to 40 days before the end of cucumber harvest. After the cucumber is harvested, the tomato seedlings are replanted, and non-self-closing late-maturing varieties with a longer growth period are selected. The tomato harvest ended at the end of November.
3. The facility vegetable stress-resistant cultivation technology integrates the facility soil ecological restoration technology system to improve the physical and chemical properties of the soil. Through the introduction and selection of high-quality stress-resistant facility vegetable new varieties, the promotion and guidance of light substrate intensive seedling raising technology, soil fertilization technology, plant adjustment Technology, water-saving irrigation cultivation technology, organic substrate cultivation technology, etc., to form an effective key technology for facility vegetable stress control.
4. Balanced irrigation and fertilization technology According to the characteristics of fertilizer demand in different growth periods and different growth seasons of facility vegetables, the farmers are guided to follow the principle of balanced fertilization, and carry out reasonable fertilization at the seedling stage, growth period, and fruiting period of facility vegetables to promote cost savings. At the same time, choose suitable irrigation equipment, according to different crops and different growth stages of water requirements, according to the need for reasonable irrigation, improve farmers' awareness of water-saving cultivation.
