Greenhouse tomato lentil three-dimensional planting technology
1 Select good seedlings, cultivate strong seedlings 1.1 Tomato selection cooperation 906, Xiafen and other early-maturing powder fruit varieties, in early November, adopt greenhouse shed nursery, 50g per 667m2 field field, sowing before sowing and soaking in warm water at 52°C 30min, kill the seeds surface germs. Sow 6~8g per square meter, dry fine soil 0.5cm thick after sowing, cover the surface of the film, build a small arch shed, close the greenhouse, increase moisture. The pre-emergence temperature in the shed is maintained at 28 to 30°C during the day, 18 to 20°C at night, and the ground temperature is 16 to 18°C. After the emergence of the seedlings, the mulching film was gently peeled off, and the fine soil was mixed to make a joint with the earth. Seedlings 2 leaves 1 heart when the choice of sunny seedlings in 10cm10cm plastic nutrients, each seedlings a seedlings, after sub-seedling moisturizing promote live tree. After easing the seedlings, attention should be paid to ventilation to prevent leggy growth. In case of continuous and rainy weather, when it is too long, 15% paclobutrazol powder (5g) can be used to spray 10kg of water, evenly spraying tomato seedlings to control high growth. 1.2 Lentils are selected for red lentils, which are marketable and well-tolerated in the market. They are used to grow seedlings in greenhouses in early January and early March, respectively, with 2 to 3 capsules per seedling. During the nursery period, watering is controlled to prevent the soil from being sterilized and seedlings are killed. In sunny days, proper ventilation is required. At night, the sheds are covered with grasshoppers for heat preservation and antifreeze. When the outside air temperature is lower than -5°C, they are to be stamped on the sheds. Layer old film. 2 Applying basal fertilization, a suitable dense planting of 1 shed for the north-south direction, about 60m in length, 5.5-6.0m in width, 0.5m in the middle walkway. 20 to 25 days before the colonization of tomato, 667 square meters of high-quality farmyard fertilizer 4000 ~ 5000kg, chicken manure 1000 ~ 1500kg, 45% potassium sulfate compound fertilizer 40 ~ 50kg, and the soil mix well, and then cover the greenhouse film temperature. In mid-February, 8 to 9 true leaves of tomato were planted on sunny days. Before the planting, every 667m2 of the plant was sprayed with 100ml of water and 40kg of water to spread the weed surface uniformly to prevent weeds, and then cover the mulch. General spacing 50cm, spacing 30cm. 3 The first phase of lentils was planted in late February in the middle of the greenhouse between the rows of tomatoes on both sides of the aisle. One shed was planted with 2 rows of lentils with 1m spacing and 1m spacing. Coverage is a greenhouse shed plus mulch, and at night the shed is covered with grass rakes to form a 4-layer cover. Phase 2 lentils were removed in the greenhouse in early April. The sheds were removed from the greenhouses. After the tomatoes were planted, they were planted. The lentil seedlings were planted on the inner side of the steel pipe frame at 15 to 20 cm, and each tube was planted with a 1-hole meter and 2 lines. . At this point, the whole greenhouse tomato planted a total of 4 rows of lentils, planting about 450 holes per 667 square meters. 3 Fine management 3.1 The temperature adjustment early in the period of appropriate high temperature suffocates the shed to promote hair trees, sunny days to keep the greenhouse temperature 25 ~ 28 °C, night 15 ~ 18 °C. During flowering and fruit setting period, it is necessary to pay attention to ventilation and cooling, and the shed temperature must not exceed 35°C. 3.2 Fertilizer and Water Management General Tomatoes before fruit set, the soil is not watering, when the growth is poor, use fine weather to chase after the application of thin organic liquid fertilizer, wait until after the first panicle set fruit, to increase the concentration of organic liquid fertilizer, every 667 square meters Rice application of urea 10 ~ 15kg, after each harvest once fruit chase once fat. In the late period of the tomato harvest in mid-June, the lentils entered the blooming stage. After every 667 square meters, 45% of compound fertilizer 15kg plus urea 10kg was applied to promote the rapid growth of soybean meal. 3.3 Biochemical regulation 1 After the flowering of the first flower head of the tomato 50%, the flower stalk was painted with a brush pen 蘸 50mgg/l anti-dropping liquid + 0.1% quick keratin mixture. 2 In early flowering period of lentils, use bud budding 3000 times liquid or 5mg/l anti-dropping liquid spray, every 5 to 7 days, even spray 3-4 times, can increase pod bean scab rate. When the lentils were harvested after the tender pods had less inflorescences, 15% paclobutrazol 8g was used to spray the leaves with 10kg of water, which increased the stem diameter of the lentils, shortened the internodes of the newly grown vines, and increased the weight of the pods. 3.4 Pruning hanging vine 1 tomato fruit set up after fruit removal should pay attention to the removal of the remaining fruit petals to prevent germ infection; timely wiping off buds, single stem stalks, appropriate fruit thinning, can improve the commercial fruit. 2 After the lentil was thrown on the first stage, each lentil seedling was hung with a transparent plastic rope. Be careful not to allow the main vine to climb to the top of the shed. When the cull is about to climb to the top of the shed, it will fall. After the lentils were planted in the second period, the tomato racks were used to pull the vines on the steel pipes, and the steel pipes were drawn into a mesh with a rope to facilitate the culturing of lentils in the middle and later stages. Usually the side buds below the first inflorescence of lentil are all wiped off. If the buds are mixed in the buds in the upper part of the main vine, the side shoots drawn by the buds should be promptly removed; if only the buds sprout, only 1～ 2 leaf topping, lateral branches can form a panicle. When the main vine grows to about 2m, it picks up its heart and triggers its side branches. 4 Diseases and Insect Pests Diseases in the fruiting period of tomato flowering are more serious, mainly including gray mold, leaf mold, early blight, and late blight. In addition to agricultural measures, appropriate pesticides should be selected for prevention and control. 65% of the molds can be selected. 600mg, 20% silver fruit 500 times, or 15% Procymidone 300g/667 square meters to prevent botrytis; use 40% of Dupont 5000 times liquid or 47% Garnett 800 times to control leaves Mildew; use of metalaxyl 500 mg solution of metalaxyl to prevent early blight and late blight. The lentils mainly include locusts, red spider mites, and soybean pods. The disease is less, and 10% imidacloprid 2000 times can be used to control aphids, and 15% broom net 2000 times liquid can prevent and control red spiders, and green kumquat 1000 times or 10 times can be used. Divide the 1500 times liquid or 15% hit 3000 times liquid alternately to prevent and control resistant insect pests such as soybean meal, Spodoptera litura. Stop medication 5 to 7 days before listing. 5 timely harvest of tomatoes in late April when the fruit is pink, harvested and marketed, at the end of June Qingtian; lentils listed in early May, when harvested, instant noodles were just exposed and did not popping is appropriate, at the end of July Teng Qingtian.
