High-yielding Cultivation Technology of Winter Tomato
Tomato is one of the high-quality vegetable varieties rich in vitamins and carbohydrates, raw and easy to grow, stable production and high yield, generally 1600 ~ 2000 kg per mu. The use of winter fields to grow a tomato is a good way to increase income. To seize the high yield and stable yield of winter tomato, according to Yangchun farmers' experience, we must grasp the following cultivation management measures: First, timely planting seedlings in the late rice harvest 25 days before sowing suitable for nursery. To plant 1 mu of tomato requires about 0.05 mu of seedbed, about 10-12 grams of seed. Seed bed plowing whitening 1 to 2 days, fine soil preparation, underfoot fertilizer, sprayed 600 times dichlorvos solution before sowing, kill soil pests, increase seedling rate. Sowing should be uniform. After sowing, the soil should be covered with fine clay or fertilizer 3 cm, and then covered with straw or pine needles. Seed beds should be kept moist to prevent excessive moisture or dryness. Combined with watering at the seedling stage, every 5 to 7 days of application of decomposed thin manure or urea solution once, so that seedlings grow robustly. Seedling period of about 22 to 25 days. 2 to 3 days before transplanting, top-dressing again. When transplanting, seedlings should be transplanted with soil as much as possible. Second, fine soil preparation, rational close planting of late rice immediately after plowing, ploughing, whitening, fine soil preparation. The tomato is a deep-rooted crop with roots up to more than 1 metre deep. The soil is deeper than 25 centimeters, and the decomposed pig manure 2,000 to 2,500 kilograms are used as base fertilizer. According to the width of 1.1 to 1.3 meters wide (baggage ditch) from the cocoon, double-row planting, 21 to 23 cm from the hole, a small row spacing of 0.6 to 0.7 meters, acres planted 2800 to 3000 strains is appropriate. Third, to strengthen the field of fertilizer and water management, improve the fruit setting rate when transplanting rooting water, improve the survival rate. After taking root, it is necessary to chase the roots and strengthen the seedlings in time. Seedling period should master the principle of diligence, and mainly liquid fertilizer, should not be too thick. With the growth of the plants, the amount of fertilizing is appropriately increased and the concentration of fertiliser is increased. Generally, fertilization is performed once every 5 to 7 days. Into the flowering period of budding, it is necessary to re-apply fruit dressing. Each mu of cooked pig cow dung 400 to 500 kg, peanut bran 15 to 20 kg, superphosphate 20 kg, potassium chloride 5 to 6 kg, fertilizer application after mixing points. When the first round of flowering begins, the second and third rounds of inflorescences are in full bloom. This is the period when the growth of tomato leaves and fruit grows vigorously. At this time, it is necessary to re-apply the fruit-bearing fertilizer and apply peanut butter 20 kg per mu and multiple compound fertilizers 25 Kilograms, 1,000 kg of soil miscellaneous fertilizer, mixed acupuncture points. After each fruit picking, topdressing once. Tomatoes in the seedling stage should not be excessively watered, otherwise it will cause appetite or cause disease. However, in the period of fruitful growth, the amount of water required is large, and in combination with topdressing, sufficient water can be used, and conditions can be used for furrow irrigation. However, avoid pouring over the top of the dome. When rainfall occurs, ditches must be drained in time to remove water. Fourth, timely pruning topping, timely removal of leggy branches and lateral buds Each inflorescence should be hanging fruit 2 to 3, excess flowers, fruits and deformed fruit should be promptly removed. When the heart is picked, leave 2 to 3 leaves after the last inflorescence. The first time the lateral shoots should be taken should be about 6.5 cm long. Fifth, pay attention to the prevention and control of pests and diseases of tomato disease, mainly bacterial wilt and late blight, etc., the early onset can be 1:1:200 times Bordeaux fluid or 50% carbendazim WP 600 to 800 times spray, every 7 to 10 One day spray, continuous spray 2 or 3 times, the control effect is better. At the same time, it is necessary to remove diseased plants in a timely manner to prevent the spread of diseases. We produce high quality of Broccoli extract, it is with best solution.
