Taiwan's early cauliflower varieties - hi II received

, 60 days after planting to harvest, the average bulb weight 700g, 667m output of 1890kg, heat and disease resistance. Height 55cm,[link widoczny dla zalogowanych], plant width is 75cm, the vertical nature of leaf, more than wax, growing vigorously,[link widoczny dla zalogowanych], fine quality bulb, white stem shank, short, Green Peduncle, good quality. Second, the cultivation techniques 1. Timely sowing of the strong heat-resistant varieties are available at Austin on March 8 ~ l0 sowing, seedling. Early sowing, at a high temperature to form the bulb poor quality, low output; late sowing is likely to cause early flower production. Seedlings in loose soil texture should choose a low water table, drainage convenient, before the cabbage and other crops not planted the land,[link widoczny dla zalogowanych], reduce soil contaminated, turn back time, drying plot. Nursery during the hot season comes, so be more Base Fertilizers beds, fine management, and use of shading, irrigation, drought and heat measures, preferably in shade net nursery. Heel in the cultivation of oyster seedlings are important, generally 18 to 20 days after sowing, transplant seedlings 1, spacing of 7 ~ lOom. Heel Water the seedbed before. This work is best to choose cloudy afternoon, so that edge transplant seedlings, while watering, while shade, so that it easy to survive. After resumption of growth of plants, fertilizer should be applied a second thin, and promote its rapid growth.

Colonization Colonization timely manner before the election should be as non-cruciferous crops, deep soil, rich in organic matter content, drainage and irrigation convenient plots. Previous Crops planted fields after harvest time in the deep plowing the soil to the soil ripening, and Shizujifei. Short growing season because of the variety of soil nutrient uptake less than the late-maturing varieties, but the rapid growth of the urgent nutritional requirements, so the basic fertilizer nitrogen should be quick result mainly manure or nitrogen fertilizers are generally mixed with humus. Human waste composting facilities generally 667m 1500 ~ 2000kg and superphosphate around 25kg. Site preparation requirements for deep groove high ridge (22 ~ 25cm) of the two-line plot. Ages 30 to 40 days is appropriate. When the seedlings when you have 5 to 6 true leaves can be planted in the field. Lifter should be multi-band soil to minimize root damage. This period of high temperature, in order to ensure the survival of seedlings, planting should be in the evening, and promptly set the root water pouring good. Line ~ 65cm, spacing 35 ~ 40cm, 667m colonization 2700. III. Field management 1. The early maturing varieties of fertilizer, and planted in high temperature conditions, so urgent and Naifei water and fertilizer requirements. This stage requires the application of fertilizer Qin Shi quick result. 5 times for top dressing. 1st in the seedling planting, new root occurs facilities In the early growth of rosette leaves, for the first 2 top dressing, add 250g per 50kg compound for pouring water facilities. Rosette leaves of 3 smaller than the growth peak, the line between the buried ditch fertilizer, urea can be mixed 10 plus superphosphate was applied after 7.5 irrigation mound. Irrigation facilities on the ground after the plant ash. 4 smaller than the initial concentration of the formation of curd cabbage topdressing fertilizer. 15kg per 667m snapped cai Shi Huang made of fertilizer, after the curd formed according to the degree look at the seedlings 1 topdressing fertilizer, and harvest of 6,000 times faster spraying with 2 or 3 times, so that took the ball neatly juicy, white and huge. 2. Irrigation water in the cauliflower, but not waterlogging hi, all the growth in the need more water, strong growth in the foliage and flowers during the ball formation, in particular, need large amounts of water. Therefore, high temperature and drought, the importance of timely irrigation. Avoid irrigation during irrigation, to be Qigou She promptly after penetration of water removal, so as not to soak too long, causing steep root phenomenon. 3. Row crop planting to the plant from the line before the closure, a total of 2 to 3 times cultivators. Cultivator prior to fertilization to avoid the loss of fertilizer,[link widoczny dla zalogowanych], pre-hoe can be deep, post-hoe Yi Qian, and to obstruct the rhizosphere soil, cultivating, weeding and more were combined. 4. Beam leaves the species during the growth period of curd, the temperature is also high, exposed in order to avoid curd, yellow or brown, so in the bud, the pick leaves when flowers are often covered for leaves. Beam leaves the leaves of the flowers around the ball straighten up, with grass gently beam tightly. Fourth, resistance to pest and disease control of the strong variety, during which 77% can be used 500 times WP killing spray to prevent the occurrence of black rot. Cultivation of high temperatures, pests and more, pay attention to pest control. The cauliflower pests are Pieris rapae, Plutella xylostella, aphids and other vegetables. Pieris can choose 15% SC 3500 times hits such as DuPont chemical control.
