The ideal soil for cultivation of small tomato is deep, fertile soil, well-drained, and relatively water-retaining. The soil pH value is 5.6%-6.7% sandy loam to clayy loam. To avoid continuous cropping of tomatoes, it is advisable to use rice, beans, corn and other crop rotations.
I. Variety selection 1. Shengyun: This variety is a mid-early-maturing variety with high temperature resistance, storage resistance and transportability that was introduced by Lihe Agricultural Co., Ltd. Middle-early life, non-stop heart, middle green leaves, strong resistance to disease, high yield, can be harvested, each fruit string 2-24, fruit weight 20 grams, fruit bulb type, rain, heat, fruit Strong, skin-resistant and crack resistant fruit, good storage and transportation, fruit green shoulder. Moderate sweet and sour taste, sugar levels up to 8 5 or more.
2, love: plant half-heartedness, heat resistance, resistance to wilt disease, moisture resistance is also strong, good meat, fruit hard, resistant to storage and transportation. The fruit has a long elliptic shape, with a fruit weight of 13 grams. The fruit is red and bright, with a sugar content of 8.5%, good taste, and good flavor.
3, Mary: plant high sex, darker leaves, anti-late blight, leaf Hui disease. Each ear can be as much as 30 or so fruit; when double dry and pruning, each node of 350 knots is a good harvest. The fruit has a long elliptic shape, and the fruit color is red and bright. The fruit weighs about 30 grams, the sugar content is about 8 or 5, and it is easy to harvest. It is not easy to crack fruit. The fruit is hard and resistant to storage and transportation.
4. Yasu No. 6: This species has a half-heartedness. The plant height is about 170 cm. The fruit is bright red, and the fruit weight is 13-15 grams. The fruit is long oval and beautiful in shape. This variety is highly heat-resistant, resistant to wilt disease, tomato mosaic disease and other disease resistance, sugar 10-11, fruit is hard, not easy to crack fruit, resistant to storage and transportation, high yield.
Second, the adaptability of small tomatoes during sowing time is stronger. Through different sowing dates, different facilities can be used to cultivate the four seasons. Small tomato field cultivation can be planted from August to February.
Third, sowing and cultivating seedlings before sowing seeds to be disinfected: If it is to prevent the early blight of tomato, soaking with warm water first 3-4 hours, then immersed in 40% formalin 100 times liquid, remove after 20 minutes Sealed for 2-3 hours, and finally rinsed with water. Prevention of tomato virus disease, the same first immersion in clean water for 3-4 hours, then transferred to 10% trisodium phosphate or 2% sodium hydroxide solution, immersed for 20 minutes to remove, rinse with water several times until the test pH is neutral can. When planting seedling bed, first apply foot water, use seed dressing with fine sand or crushed soil, spread evenly on the seedbed, cover 0. 5 cm thick loose soil. When the seedlings grow 2-3 true leaves, the seedlings must be planted, and 5-6 true leaves can be transplanted.
4. Soil preparation, planting, and transplanting The former planters had not planted solanaceous plants and lands that were convenient for irrigation and drainage. After the land was cultivated, the planters were planted at a row spacing, followed by basal fertilization and sorghum, and the principle of north-south orientation. The width of the plant is 1.4-1.7 meters (including the ditch), the spacing between the plants is 45-55 cm, and the planting area is between 1,600 and 2,000 plants per acre. Choose strong and healthy seedlings and plant them.
V. Field Management 1. Reasonable fertilization irrigation Little tomato roots are well developed and thrive, fertilizers are mainly organic fertilizers, combined with compound fertilizers, and potassium fertilizers are appropriately added.
2. After inserting the seedlings and planting the seedlings, the vines shall be promptly inserted into the vines, and the early-maturing self-sealing top cultivars shall be inserted into the low shelf and the height shall be less than 1 meter. Elevated species, height above 1.5m. Generally inserted into the stand and stand, the bar should be strong and solid to prevent lodging. Tied vines tied the stems from the upper part of the first panicle to the shelves, and then tied every 2-3 leaves later. The vines should be tightly attached, and when the plants grow vigorously, they should be tied tightly; the weak ties should loosen.
3, pruning squatting according to the growth of tomato, can be divided into single stem pruning and double dry pruning two methods. Only dry trunk, and all the lateral buds removed, double dry pruning is in addition to the main trunk, leaving only the first inflorescence of a lateral branch below the leaves, the other side buds all erased, picking buds should pay attention to as soon as possible, the best choice for sunny. Keep the wound dry and avoid the infection of the bacteria. If it is raining, spray it immediately after the operation to prevent the disease.
6. To harvest the tomatoes according to the characteristics of different varieties to achieve the harvest when the fruit is ripe, over-harvest harvest is not conducive to storage and transportation
