Zucchini cultivation techniques

Seedlings of Zucchini are about 45 days old (5 true leaves). The spacing of the planting rows was 3.3 cm each, and the height of the seeds was about 3 cm. The spacing of the transplanted rows was about 10 cm each. Seed temperature control, from sowing to unearthing, temperature 25 ~ 28 °C, night temperature of about 12 ~ 15 °C. After 3 days of unearthing, the temperature should be reduced to 23 ~ 25 °C, night temperature dropped to 10 ~ 12 °C, to prevent seedlings grow. In the late stage of nursery before planting, the night temperature can be reduced to below 10°C, or even 6-8°C, and the seedlings can be adjusted to adapt to open conditions. Planting or sowing according to a certain standard Fertilizer amount spread base fertilizer first, and then deep plowing, rake flat, early cultivation must set up the wind barrier, and then to make rake, generally 畦 width 1 to 1.6 meters, 7 to 10 meters long, line spacing due to type and different The dwarf types range from 0.8 to 1X0.4 to 0.5 meters, with 1,300 to 2,000 plants per acre, and the arboreal species, 1.6X and 0.5 meters to 800 plants per acre. The method of colonization can be water stable seedling method. Seed germination first soaked in live broadcast, selected sunny, warm when the sowing or sowing. Field Management (1) Management of Soil, Fertilizer, and Water After the zucchini has grown slowly, it should be combined with topdressing to pour water once. This time, the water should be poured into dark water, and then the seedlings should be planted. After seedlings, the most critical factor is the sooner or later, so early will be crazy, will fall late, will grow to 6 to 10 centimeters long in root melons, when the melons poured water more appropriate. After the number of watering and watering gradually increased. (2) Other types of management Generally, dwarf types do not need to be pruned, while the type of creeping must remove all lateral branches in time, leaving only the main vine. Squash rely on natural pollination, the result rate is not high, it should be artificial pollination to increase the rate of results. In addition, 30-40 ppm of 2,4-D can be applied between the base of the flowering style and the base of the petals to increase the rate of fruit and fruit weight. Diseases and pests control Squash virus disease occurs more serious, in the absence of specific effects of the case, from the point of view of cultivation and prevention, most of the effective spring ahead, fall after the wrong approach to deal with the virus disease hazards.
