Cultivation techniques for hard-toothed tomatoes during summer

I. Suitable varieties and varieties of cultivars suitable for planting in our province during the summer are mainly Bailey, Grey and Braun, etc. Generally, they are raised from the end of May to the beginning of June, and are planted at the beginning of July, and harvesting is completed in the middle and late October. The greenhouses are planted with shade nets and insect nets to prevent rain, shade, and insects.
Second, nurturing strong seedlings using nutritional seedlings nursery, it is best to use nutritious block seedlings. 6 kinds of pastoral soil without pests and 4 parts of decomposing circle fertilizer without sowing of solanaceous crops, plus 3 kg/m3 of NPK fertilizer, 30-40 g/m3 of 50% carbendazim powder, or 65% Manco manganese zinc powder 80 g / cubic meter mixed, smashed sifted, sealed with plastic film 2 to 3 days sterilization. Prepared nutritious soil is ready for use. Seed disinfection, soaking in 10% trisodium phosphate solution for 30 minutes, soaking in 1% potassium permanganate solution for 15 minutes, removing the seeds, washing with water and drying to sow. Pay attention to placing the seeds flat, and the cover soil should not be too thick, generally 0.8 cm. Since the nursery is in the high temperature season at this stage, nursery beds should be covered with shade nets and insect nets. Seedling humidity control should be controlled to see dry see wet, and moderate air release, no longer dry leaves do not pour after the emergence of true leaves, to prevent the occurrence of disease. The diseased seedlings were found to be removed in time, and Hymexin WP or Preclosure was used for chemical control.
Third, timely colonization, appropriate thinning when the seedlings 3 leaves 1 heart when planting. In order to prevent field closure and premature senescence, moreover summer cultivation should be sparsely planted with 1600-1800 plants per acre. Using sorghum cultivation, plant spacing 45 to 50 cm, row spacing 75 to 80 cm; Shizu base fertilizer, applied per acre decomposed chicken manure 5 to 6 cubic meters, ternary compound fertilizer 70 to 80 kilograms, superphosphate 30 to 45 kilograms, planting After 3 to 5 days, 72.2% Preclosure 800 times solution was sprayed or rooted to prevent disease.
Fourth, strengthen field management
1. Watering. Over summer cultivation is mainly promoted in management. The water should be poured hard and keep the field moist. Watering in the morning or evening is appropriate.
2. Fertilization. When the second panicle grows to the size of the walnut, NPK fertilizer is applied 15 to 20 kg per mu. Every time a fruit is topped once. In the middle and late stages of growth, foliar spraying of 0.2% potassium dihydrogen phosphate was performed once every 10 days and sprayed for 2 to 3 times.
3. Pruning. Single stalk pruning method. Per plant, 6 to 7 ear fruit topping, fruit 4 to 5 per panicle, and removal of excess fruit, fruit removal should pay attention to the first fruit of each ear fruit, is conducive to improve a fruit rate. When the first ear fruit is large, one or two leaves are left under the ear, and all other leaves are destroyed.
4. Harvest in time. Summer cultivation is a season of high temperatures. To prevent rotting, harvesting should begin immediately when the fruit surface begins to turn red.
