Tomato is one of the high-quality vegetable varieties rich in vitamins and carbohydrates(20cm plastic grow pots). It is easy to grow and produce high yield. It generally produces 1600-2000 kg per mu. At this time, planting a tomato with winter leisure fields is a good way to increase economic income(propagation tray). In order to capture the high yield and stable yield of winter tomato, according to the experience of vegetable farmers, the following several management measures should be taken: timely seeding and seedlings should be planted for about 25 days before the late rice harvest.(3 gallon black plastic nursery pots wholesale)
The seedbed is plowed and whitened for 1 to 2 days(23cm plastic grow pots). Fine soil preparation, lower foot fertilizer, spraying 600 times of dichlorvos liquid before planting, killing soil pests and increasing seedling emergence rate. Sowing should be uniform, cover 3 cm with fine mud or mud after sowing, covered with straw or pine needles. Keep the seedbed moist and prevent excessive or dry water(plastic nursery pots wholesale). In the seedling stage, combined with watering, every 5 to 7 days, the decomposed thin human excrement or urea solution is applied once to make the seedling grow robustly.
After rooting, you must finely plan the land, and properly plant the late rice after the harvest(6.35cm square grow pots). Immediately after the harvest, plow the white and finely prepare the land. Tomato is a deep-rooted crop. The roots can reach more than 1 meter in the soil. The soil layer should be deeply ploughed by more than 25 centimeters, and the 2,000-500 kilograms of fertilized pig and manure should be used as the base fertilizer(black plastic nursery pots). Later, according to the width of 1.1 to 1.3 meters (the ditch), the double row planting, the hole spacing is 21 ~ 23 cm, the small row spacing is 0.6 ~ 0.7 meters, and the planting of 2800 ~ 3000 plants is suitable.
(3 gallon black plastic nursery pots wholesale)In the main seedling stage, it is necessary to master the principle of diligent application of thin and thin, and mainly based on liquid fertilizer, and should not be too thick(8.89cm square grow pots). At the same time, with the growth of the plant, the amount of fertilizer is increased and the concentration of the fertilizer is increased. Generally, the fertilizer is applied once every 5 to 7 days. When entering the flowering period of the bud, it is necessary to reapply the fruit fertilizer(plug trays wholesale). 400-500 kg of fertilized pig cow dung per mu, 15-20 kg of peanut bran, 20 kg of superphosphate, 5-6 kg of potassium chloride, and then mixed with fertilizer.
When the first round of flowers begins to bear fruit, when the second and third round inflorescences are in full bloom, it is the stage of tomato leaf growth and fruit growth(11.43cm square grow pots). It is necessary to re-apply fruit fertilizer, 20 kg of peanut bran per acre, 25 kg of multi-component fertilizer, The soil is mixed with 1000 kg of fertilizer. Pick each fruit once and topdress once. However, the amount of water required for the fruiting period is high(plastic nursery pots manufacturers). It is necessary to combine the topdressing with the water, and the conditions can be used for furrow irrigation, but it is not allowed to fill the dome.
(3 gallon black plastic nursery pots wholesale)When picking the heart, 2 to 3 leaves should be left after the last inflorescence(11.43cm square nursery pots). The first extraction of the lateral buds should be carried out when the lateral buds are about 6.5 cm long. The diseases of tomato include bacterial wilt and late blight. In the early stage of the disease, it can be sprayed with 1:1:200 times Bordeaux mixture or 50% carbendazim WP 600-800 times, and sprayed once every 7 to 10 days(wholesale nursery pots). Spray 2 to 3 times, the control effect is better. It is necessary to remove the diseased plants in time to prevent the spread of the disease.
