And can bring considerable economic benefits to the farmers now Walled winter temperature broccoli cultivation techniques are described below: l Choose varieties Green Ridge strong growth potential than the average variety, good quality, high yield and disease resistance, cold strong, suitable for greenhouse winter cultivation. 2 September broccoli seedlings in mid-winter and spring 11 can be sown in mid-bed general nursery 10m, enough to base fertilizer should be applied before sowing and nitrogen fertilizer complex units. The nutrient supply of seedlings to ensure its water foot of water. Until the water seepage, the use of screening uniformly blending fine soil and seed sowing. After sowing casing 1 ~ 1.5era. Bed temperature maintained at 20 ~ 23 ��,[link widoczny dla zalogowanych], 10 �� minimum of not less than the outside temperature dropped later due to be deducted Small Shed Chuangtu moist. To Bao Miaoshun profit growth. Seedlings of the standard thick stem. Stem diameter O, 4 ~ 0.5cm. Leaves dark green hypertrophy. With 5 to 7 true leaves, compact plant morphology, root intact. Ages 30 to 35 days. Before planting, seedling stretch of 2 to 3 days in advance water lifter, and then store seedlings with soil. 3 fertilization on soil soil preparation broccoli strict requirements, but included very demanding of soil nutrients. The growth process. Need plenty of fertilizer before planting. Quality basic fertilizer applied per acre (driving other farmyard manure composting chicken manure) 4000 ~ 5000kg, P] 00kg. Urea 25kg. Then Gengba uniform. Zuoqi. Qikuan 120c'm,[link widoczny dla zalogowanych], a ridge of a furrow, ridge width 70era. Groove width of 50cm. 4 colonization in order to improve the temperature, promoting Huanmiao. Should be 15 to 20 days before planting to warm mm film covering a good, sealed in plastic film before colonization grilled 7] 0 days laid out for planting method using perforated planted seedlings of each ridge 28 * double. Plant spacing 50cm, cut shallow water when planting,[link widoczny dla zalogowanych], transplanting seedlings to water stable 5 to 7 days after pouring Huanmiao water. Row crop cultivators after time. 5 after planting, fertilizer and water management. To promote plant growth as soon as possible so that it formed before the ball is now adequate nutrition leaf area, leaf area is certain to win the key to so yield, growth and seedling survival to make the initial first; the second plant to make fertilizer during this period, strong growth , in order to promote water on to the main. Dressing in the first 15 to 20 days after transplanting or about, Mushi NPK fertilizer 25 ~ 30kg; second top-dressing in the top bulb appears, acres of NPK fertilizer topdressing 15 ~ 20kg; after the close of each a flower ball.

Economic losses. Curd harvest standard is closely square. Bud particles is small. The color green. Harvest to remove the spent cutting the net J n {film, stems not stay too long, should not be stored after harvest. Timely market.
