Cultivation Techniques 1. Nursery Dry seeds and seed sowing are not in direct seeding and germination is required. Germinate seeds 2 to 3 hours before germination, then soak in warm soup. Put the seeds in warm water of 55°C for 15 minutes, stirring constantly, then wash them with warm water at 30°C, continue immersing for 4 to 5 hours, remove and drain the water, wrap it in a clean damp cloth and place it under 25～30°C Germination. When the seed length is 1/2 of the seed diameter, it is sown in a 72-well plug tray pre-mounted with a matrix. The non-budding concentrated seeding is used as a supplemental seedling backup. After sowing, the cover matrix is ​​0.5 centimeters thick and the seed amount is 3 packets per acre (1000 capsules/bag). ). Move the plug tray into a plastic greenhouse built in advance and cover the plastic film after watering. The temperature was maintained at 25-28°C before emergence and 15-18°C at night. 70% of the seeds were removed in time after emergence. After emergence, until the first true leaf appeared, the temperature was controlled at 22-25°C and nighttime at 16-18°C. After the first true leaf is unfolded, the temperature is controlled at 25 to 30°C and at night at 18°C ​​or more. Watering every morning after emergence to keep the matrix inside the plug wet. 1 leaf 1 supplement nursery special fertilizer, pouring 0.5% nutrient solution. Ventilation was strengthened 1 week before colonization, and the temperature was gradually lowered for hardening. Strong seedlings standard: seedlings robust, top not flat, height 15 cm; 7 true leaves, dark green leaves, leaf hypertrophy; thick stems, diameter 0.6 to 1 cm, short internodes, well-developed root system, number of lateral roots Multi, white; no pests, no mechanical damage. 2. Colonization It is cultivated on high ridges and covered with film. The ridges are 10 to 20 centimeters in height, 80 to 85 centimeters in ridge width, 100 to 110 centimeters in ridge width, and 50 centimeters in furrow width. Both sides of the mulching film are buried 2/3 to 3/4 down the ridge roof. When ridges are built, ridges should be slightly higher to facilitate tight membranes. Seven days before colonization, a two-color plastic film covering 110 cm wide was used. The inside of the membrane was black and the outside was silver-gray. Before mulching, the soil in the ridge should contain sufficient water. Tidal land is generally well-hydrated and has more rainfall, which can be covered by rain. At the time of transplanting, 2 rows were planted per ridge, and the spacing between the rows was 40-50 cm. 3. Field management (1) Water and fertilizer management When planting watering planting water, 1 liter per plant, every 7 days irrigation 1 time sapling water, bogey flood irrigation. When the first panicle grows to the size of the hen's egg, it starts to water according to the weather conditions. Usually it is filled for about 7 days and the surface is kept dry. Pay attention to drainage during the rainy season to prevent excessive humidity from aggravating pests and diseases. Tomatoes need a large amount of fertilizer, in order to ensure high quality and high yield, we should ensure adequate nutrition supply. In order to increase the yield and improve the fruit quality, organic fertilizers should be added, and appropriate fertilizers should be applied. The application of organic fertilizer can improve the structure of soil aggregates, optimize the population of colonies in the soil, and reduce the occurrence of physiological diseases of umbilical rot. The ground-based basal soil fertilizer is mainly applied as an applicator, with 3 to 5 cubic centimeters of organic fertilizer per acre, 50 to 100 kilograms of superphosphate, 100 kilograms of compound fertilizer (15 to 15 to 15), 25 to 30 centimeters deep, organic fertilizer. 2 years can be applied. After the first ear began to enlarge, 15 kg of fast-acting potassium nitrate was applied per mu, and when the third ear started to enlarge, 20 kg of potassium nitrate was quickly applied per mu. After planting, the topdressing nitrogen and potassium were heavier in the early stage and potassium fertilizer was added in the middle and later stages to facilitate fruit enlargement and transformation. Partial application of nitrogen fertilizers should not cause physiological calcium deficiency and cause umbilical rot. Normally, fertilizer is applied before it rains. Insufficient rainwater must be filled with water. (2) Framed vines Bamboo rafts are used to support the human frame and tied with rifled guns. When tying the vines, the inflorescences are parallel to the rows and placed under the leaves to reduce exposure. The tomato root system is developed and the growth rate is fast. Lateral branches should be removed in time to reduce nutrient consumption. Single stem pruning can improve the commercial fruit and fruit evenness of the tomato fruit, the main vine results do not leave lateral branches, and focus on knocking out the lateral branches of each flower, each plant can leave 5 to 6 ear fruit, and finally 1 ear fruit leaves 4 leaves topping. 4. Harvest Summer and autumn tomato coloring faster than spring, easy to mature, easy to soften and metamorphose, close sales should be harvested after the fruit began to turn red; long-distance transport, should be harvested during the white maturation period or color change. Pest Control 1. Disease (1) Viral disease Strictly control aphids and whiteflies to reduce the chances of plant infection; use 20% hydrochloric acid morpholinium WP to prevent virus disease in advance and spray 7 to 10 days for a total of 2 to 3 times, which should be avoided. At noon high temperature medication, such as after treatment within 4h of rain, need to re-spray; found that susceptible plants should be promptly cleaned. (2) Stem rot The diseased area began to be dark brown, and then expanded around the base of the stem for 1 week to rot the cortex. The aboveground leaves turned yellow and wilted, and the whole plant withered. Can be used 50% dimethomorph WP wettable powder 1000 times Irrigation Pan Irrigation, with medicine colonization; After colonization, 50% Dimethomorph WP can be used to prevent 1500 times foliar spray. (3) Early blight 77% can be used to kill the wettable powder 600 ~ 800 times liquid spray prevention; early disease can be used 78% Cobo WP 500 times spray control, 8 to 12 days spray 1, even spray 3 times. (4) Umbilical rot Partial application of nitrogen fertilizer causes physiological calcium deficiency, long-term high temperature and drought can cause umbilical rot. Organic fertilizers should be added to regulate the proportion of nitrogen fertilizers. 2. Insect pests (1) Locust, whitefly Aphid adults and nymphs damage tomato leaves and growth points, resulting in leaf curling, growth stagnation; whitefly is generally clustered on the back of the upper tender leaves, sucking sap harm, resulting in yellow leaves deformed. Aphid and whitefly have serious damage and often cause virus disease. They can be treated with 10% imidacloprid WP 2000 times solution or 10% bifenthrin EC 3,000 to 5,000 times solution. (2) Cotton bollworm In the summer, the main pests eat larvae, flowers and fruit with larvae and also harm the tender stems, leaves and buds. Pre-winter ploughing of land to reduce overwhelming insect sources; 1 black light per 3.33 hectares to trap and kill adult worms, with significant effect; According to insect report, during the prosperous period, combined with pruning and removing eggs, burned; Before the deadline, the pesticide was applied in the morning and the upper part of the plants was sprayed. The BT thuringitic bacillus preparations could be used for prevention and control. Continuous control was performed twice and the control effect was good. In addition, the fruit of the gall was also removed in time. Fufeng Sinuote Biotechnology Co.,Ltd. , https://www.sinuotebio.com
