The efficient optimization of planting patterns of Dutch beans, tomatoes and vegetables can maximize the use of space, light and heat resources, enhance disease resistance, increase yield and quality, and achieve maximum economic benefits.
First, the tomato:
1. Selection. You can choose high-quality and high-yield products such as “Su Kang No. 5â€, which is suitable for mid-maturing cultivation in summer.
2. Site preparation. Choose fertile and loose sandy soil, apply 1500 kg of decomposed manure per acre, 60 kg of decomposed cake fertilizer, and 50 kg of ternary complex fertilizer.畦 Width 2 meters, each 畦 2 combination, each combination of spring planting 2 rows of tomatoes, the average plant spacing of 50 cm 38 cm, 3500 plants per acre.
3. Sowing at the right time. In the middle and late March, the film was kept in heat preservation (the seedlings were long-lived with 5010-6 concentration of paclobutrazol), and planted in late May. Roots should be planted, watered after planting, and moistened with soil.
4. Fine cultivation. After waking up the tree, combine the loose soil and apply a thin water dung seedling early. During the flowering period, the drug is scented, and after the fruit is placed, 800 kg of decomposed and diluted water dung is applied per acre, and the appropriate amount of "expanded fruit fertilizer" is applied. Initial flowering frame (1.2 meters high), tied vines, pay attention to rational adjustment of plants, timely pruning (snoring, sparse flowers and thinning, topping, leaving 2 to 3 leaves above the top inflorescence) and go to the old leaves to concentrate Nutrients, promote precocity, improve quality.
5. Control pests and diseases. Spraying 500 times 64% anti-virus cockroaches 2 days after planting to control the occurrence of early blight and leaf mold; 200 times 2% agricultural resistance, 500-600 times 4% agricultural anti-12 melon tobacco type control leaf mold, gray mold Application of special effect gray mold to control gray mold, disease; eliminate dry spirit plus 50% carbendazim wettable powder plus green wind 95 with 500 times liquid root irrigation (150 ~ 200 ml per plant) control of wilt disease Disease); virus clear 300 times liquid plus double-effect micro-fertilizer to prevent viral diseases; 45% chlorothalonil smoked smog to control anthrax.
Second, green vegetables: interplanting in tomato fields.
1. Selection. Choose high-quality, high-yield and disease-resistant "anti-hot green" and "small leaf green".
2. Plant at the right time. After the tomato was planted in the end of May, it was immediately planted in the line, insisting on the sowing of the seedlings, sowing the hands and spreading the hands, keeping the seedlings out, paying attention to the fertilizer and water management in the growing season, small fertilizer and water, light pouring and pouring.
3. Control pests. After emergence, the high-purity and low-toxic pyrethroid pesticides are selected, and the wine is sprayed once every 4 to 5 days, and is stopped 7 to 10 days before harvesting. The various pesticides are used alternately to prevent yellow stripe and cabbage caterpillars.
Third, green garlic:
1. Selection. Choose early-ripening, high-quality, high-yield "two water early", "March yellow", etc., before the sowing, choose white, fat, non-destructive garlic cloves for seeding, 3 kg per mu.
2. Sowing at the right time. Autumn green garlic is planted in late August after harvesting of peas. The garlic is stored at a low temperature (2 to 3 ° C) for one month before sowing. When planting, insert the garlic clove directly into the soil 1/2, cover it with fine soil or gray fertilizer.
3. Scientific management. Spraying chemical herbicide weeding after sowing (50 grams of 25% herbicide ether per acre to 50 kg of water), covered with wheat straw, timely watering in case of drought, help seedlings unearthed. In the three-leaf period, 1000 kg of decomposed manure is used per mu, and the appropriate amount of quick-acting nitrogen fertilizer is applied to the water to facilitate early initiation. In the future, every 7 to 10 days, the decomposed and diluted water feces will be applied again, and the seedlings will be promoted. When the growth period is dry, it should be watered and moisturized.
Fourth, the Dutch beans:
1. Selection. It mainly uses "two flower species" which are cold-tolerant and drought-tolerant, with a total growth period of about 150 days, emergence to 60 days of planting, plant height of 180 cm, main stem 27 to 32 knots, branching 2 to 3 knots, main section At the peak of the pods at 13-14 knots.
2. Topdressing. Combined with loose soil, 2 to 3 times of decomposing and dilute water manure (600 to 1000 kg per mu).
3. Broadcast early in time. The suitable temperature for the growth of the Dutch bean (two flower species) is 9 to 23 ° C. The sowing time is from the end of October to the beginning of November, and it is broadcast early in time, with a long growing period and high yield. In late October, the green garlic will be opened after the harvest.
4. Scientific management. After sowing, the soil is covered with soil and fertilizer. After the sixth section grows, the fertilizer is applied once every 8 days. 250 g of calcium, magnesium, phosphorus and urea are applied to 50 kg of water, and the leaves are sprayed 2 to 3 times in the flowering and pod-forming period. Nitrogen fertilizer. At the peak of picking, the amount of fertilizer needed is large, and it is applied once every 5 to 6 days with 1% compound fertilizer for 4 to 5 times. At the end of the pod-forming period, the flowering is weakened, and every 8 to 10 days, 400 g of calcium magnesium phosphate, 250 g of urea and 50 kg of water are added to enhance the function of the leaves and improve the yield. The Dutch beans are sensitive to water, and the flooding is prone to premature aging. In case of rain, it is necessary to drain the ditch in time.
5. Control pests and diseases. Powdery mildew is the main disease, which occurs in the first month of the month. It is mainly used for prevention and control, sprayed with 50% sulfur suspension agent 300 times per acre, or sprayed with powder rust. The insect pests are mainly aphids and leaf miners, which are sprayed with 40 kg of water with 40% omethoate emulsion or 2.5% deltamethrin 30 ml.
