From August to September every year, the market for tomatoes is off-season, and the price is similar to the price of protected cultivation. Therefore, it is a good way for farmers to make a fortune by investing in small-scale investment, high efficiency, and large market potential. The key management techniques for planting summer tomatoes are summarized as follows: First, select good varieties. Through comparative experiments, I believe that the two varieties of Selster and Xinlvfeng Hybrid 2 are more suitable for cultivation in summer. Their characteristics are: early maturity, unlimited growth, small leaves, average fruit weight of about 300 grams, and high fruit setting rate. , Strong disease resistance, less cracking fruit, tenacious resistance, pink fruit, welcomed by consumers. The new Lvfeng hybrid No. 2 anti-cracking fruit racer almost. Second, nursery. According to experience, it is the best time to raise seedlings in late April every year. A well-drained plot is used for the nursery site, and 3:7 blending is performed with the decomposed high-quality ring fertilizer and the grain field ripe soil. After watering the seedlings, the seeds are broadcast live in the seedlings and the seedling period is about one month. Third, soil preparation and fertilization. The tomatoes in summer are suitable for the cultivation of shady slopes, highlands, well-ventilated areas, arable lands, drought-irrigated land, and thick soil layers. The formula fertilization is used to apply sufficient basic fertilizer, and 5,000 kg of good-quality ring fertilizer is used per mu. 60 kg of potassium sulfate compound fertilizer was spread evenly, and the soil was deep-smashed to make earthworms. Fourth, cultivation methods and density. The method of ridge and sorghum cultivation is conducive to drainage, with a width of 1.2 meters per plant, a row spacing of 0.37 meters and 3000 trees per acre. Fifth, cultivation and management. After planting, apply 50 kg of cooked cake fat per acre. In a timely manner, cultivating the grass until the seedlings grow to 0.3 meters in time, and insert and hold the seedlings in time. Insertion method: triangle, square can be, inserts should be firm. Each fruit 4-5 spikes, leaving 3-4 fruit per panicle. After flowering, flowers or flowers are sprayed in a timely manner. Spraying with water-drops is best once every three days. VI. Common Diseases and Insect Pest Control 1. Viral disease: soaking with virus A, plant disease spirit and 0.1% potassium permanganate solution, wash and sow with water after 15 minutes. The seedling stage or after planting with "NS-83" booster 100 times, or 20 times with raw bean juice, the prevention effect is also good, spraying 3-4 times from the seedling stage to the flowering period. Prevention is the main, supplemented by treatment. 2, sooner or later, the epidemic disease: use the early epidemic late epidemic 800 times the liquid, or Du Bang Kelu 600 times liquid, add red and big, green Fenwei 1-3 or love to receive or 1% of calcium nitrate and other rotation use. 3, stalk rot: bacterial kill or agricultural streptomycin or stalk rot, etc., when spraying pesticides added pyrethroid cabbage Pieris. 4, gray mold: use fast-king powder or anti-mildew WP plus foliar fertilizer, pyrethroid insecticide, spray evenly in the afternoon on a sunny day. Seven, timely harvest. Look at the weather forecast in time for the harvest. Put the eight mature fruits in the house before the heavy rain comes. Pick the handles for sale to prevent cracking. One day before the next frost, the white ripened fruit was picked off and placed on the inside, wrapped in a thin film and put on the market.
