Greenhouse tomato and lentil three-dimensional planting technology

Greenhouse tomato and lentil three-dimensional planting technology

1. Choose good breeds, cultivate strong seedlings 1.1 Tomato selection cooperation 906, Xiafen and other early-maturing powder fruit varieties, use greenhouses in early November to raise seedlings, prepare 50g per 667m2 field field, sowing before drying and use 52°C warm water Seed soaking for 30 minutes to kill germs on the seed surface. Sowing 6--8g per 1m2, cover 0.5cm of dried fine soil after sowing, cover the surface of the mulch, set up a small shed, close the greenhouse, and moisturize. The pre-emergence greenhouse temperature is maintained at 28--30°C during the day, 18--20°C at night, and the ground temperature is 16--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 sub-seedlings in 10cmx10cm 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. 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. Apply basal fertilization. A large shed is reasonably planted in a north-south direction with a length of about 60m, a width of 5.5--6.0m, and an intermediate walkway of 0.5m. 20--25 days before the planting of tomato, apply 667-5000m2 of quality farmyard fertilizer per 667m2, chicken manure 1000--1500kg, 45% potassium sulfate compound fertilizer 40--50kg, mix well with the soil, and then cover the greenhouse film. Warming. In mid-February, 8--9 slices of tomatoes 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 from the greenhouses in early April. The sheds were removed from the greenhouses. After the tomatoes were planted, the plants were planted. The lentil seedlings were planted on the inside of the pipe rack at the bottom 15 to 20 cm, and each tube was planted with a 1-hole planter. Row. At this point, the whole greenhouse tomato planted a total of 4 rows of lentils, planting about 450 holes per 667 square meters. 3. Precise management 3.1 Properly conditioned temperature in the early stage of the temperature adjustment. The greenhouse is maintained at 25--28°C during the day and 15-18°C at night. 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 Increase the 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 adjustment 1 tomato first flowering 50% after the flowering, with a writing brush 蘸 50mg / L anti-dropping liquid + 0.1% fast-King mixed coating stalk. 2 In the early flowering period of lentils, use bud buddha 3000 times liquid or 5mg/L anti-dropping liquid spray, every 5-7 days, spray 3 to 4 times successively to increase pod bean yield. 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. Generally, the lateral buds below the first inflorescence of lentils are all wiped off. If the buds next to the flower buds are mixed in the upper part of the main vine, the side shoots that are drawn by the leaf buds should be promptly removed; if only the leaf buds are germinated, only one is left. - 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 Infestation of tomato during the fruiting period results in more diseases, mainly including gray mold, leaf mold, early blight, and late blight. In addition to agricultural measures, appropriate pesticides should be selected for prevention and treatment. Mildew spirit 600 times liquid, 20% silver fruit 500 times liquid or 15% procymidone 300g/667 square meters control gray mold; use 40% DuPont Fuxing 5000 times liquid or 47% Garnett 800 times liquid Leaf mold; using metallomethacinate 500% 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 5-7 days before listing. 5, timely harvest of tomatoes in late April when the fruit is pink, when harvested and listed at the end of June Qingtian; lentils listed in early May, harvested when the instant noodles beans just emerging and bundled up is appropriate, at the end of July Teng Qingtian .
