Death. Control Methods: nursery deep plowing in winter, the eradication of overwintering cocoon; newly hatched larvae of spraying pesticide pollution, such as diflubenzuron 3 1O0 ~ 3000 times, 6000 times diflubenzuron, l% mites cleared 20,003,000 times; 6 - October between the people]: Abstract mites cut package, focused on burning; activities have not yet started when the larvae form a network nest. Crystal with 90% of the 4,000 to 5,000 times Pensha trichlorfon, such as the larvae have formed a network nests can be removed manually burned. 4,[link widoczny dla zalogowanych], powdery mildew: in the high temperature, humidity, poor ventilation environment most prone to start seedlings leaves the back of the gray-brown spots near the main vein, later spread to the dorsal, and the emergence of a layer of white powder. Control methods: Note nursery hygiene, proper thinning seedlings, found that diseased plants should be burned immediately; disease occurs, with a 03 Baume degrees to 0.5 degrees of lime sulfur, sprayed once every 10 days, the three consecutive spray. Four times. (Author: 225400 Taixing Town, Taixing City, Jiangsu Province, agricultural extension services in the 0, Taixing City Forestry Bureau) is a hi dry fodder beet crops, the fear of floods, water consumption of 200 cubic acre sugar beet is about saving more than 60 120 square wheat , in particular, drought-resistant sugar beet seedlings, 4 to 6 to alleviate the peak month of spring irrigation water pressure is significant. Another high yield of fodder beet, feeding livestock and poultry significant effect, crop structure adjustment is the preferred water-saving crops. I, formation, reduced irrigation surface. First of all channels should be selected away from the edge of the lake, higher ground dry stubble cultivation, not with the hi water adjacent to planting crops. Hirata before sowing soil preparation, whichever is higher pad is low, so that height does not exceed 2 to 5 cm of irrigation to 0.3 to 0.5 acres Qimian appropriate. 2,[link widoczny dla zalogowanych], use water-saving varieties. Choice of imported varieties FF10000, but also domestic varieties can be fed Long l number. 3, drought planting, ensure that all seedlings (1) Soaking or mud pie bag types of uncoated seeds with warm water and soak 1 to 2 days or planting the seed with a mud pie when the package. Use of damp or rain in late April, grab moisture seed. (2) take water o'clock. Plots on poor soil moisture, the first ditch, doused with water in the ditch, and then planting casing. To prevent the running entropy, but also with a diameter of 5 to 7 mm small wooden sticks, a nib, marked a profound degree of sowing, watering hole after planting. (3) plastic film mulching. Mulching can significantly improve the top soil temperature, inhibition of salt increased, reducing salt damage. Significant effect in the early growth stage, according to the determination, make 4 to 6 month of ground temperature increase from 1.35 to 4.490 (2, 3 to enable the emergence of sugar beet as early as 7 days, Seedlings increased by 20%, and conducive to the rapid growth of seedlings , but later due to its moisturizing function of temperature conducive to the occurrence of disease, is very unfavorable to the growth of sugar beet, it is proposed ridge closure before the time torn off plastic film (4) ridge types of furrow irrigation. beet crop is a low seeding density, more suitable for ridge species of irrigation, Ridge species can reduce the sugar beet easily understood by environmental humidity caused by disease, and conducive to root growth, significant effect of furrow irrigation water, the general ridge height l5 ~ 20 cm, can be the first ridge after planting, cultivating, can also be combined with renewed after emergence ridge (5). seedling transplanting, delay planting. Fodder beet sowing date can be from 4 to 7 months late, such as the pre-irrigation soil moisture conditions of poor nor the place, according to the inflow time, the use of seedling transplanting , in the lee sunny nursery optional, flat, fertile soil loose place, bed planting seedling per mu 2.5 to 4 kg seeds, 5 to 8 acres of field for transplanting. When the seedlings when 2 or 3 leaves transplant , or the extension of the method of sowing cultivation of drought relief. 4, the control density. beet strong growth potential of the individual, lush foliage, and fallen large, larger nutrient area, but the density less than, evaporation capacity, is not conducive to water saving ,[link widoczny dla zalogowanych], the general number of trees to a single species of acres of 3500 4000 is appropriate, select the line spacing 50 �� 30 cm or 60 �� 30 cm. intercropping sugar beet when the bandwidth of 95 ~ 100 cm kinds of acts should be two adjacent broadcast product line was the word among strains Implant. 5, strict control of irrigation. prophase depends on growth of the seedlings do not dry without irrigation; medium with fertilizer in mid-June, mid July 1 of the irrigation water (in case of irrigation-free medium to heavy rain), field water shall not more than 8 hours; in the late dry soil, at noon when the leaves Danian reperfusion l water, 25 to 30 days before harvesting to stop irrigation. the whole growth period of 3 to 4 times of irrigation. 6, rational fertilization, water by fertilizer. recommended per acre basis 4-5 tons of organic fertilizer, ammonium bicarbonate 5O kg,[link widoczny dla zalogowanych], 40 ~ 5O kg superphosphate, potassium sulfate 2O ~ 30 kg, 2 kg of borax, diammonium phosphate fertilizer types 5 to 7 kg, dressing twice, in mid-June 7 irrigation per acre in mid-chase with 10 ~ l5 kilograms of urea and 7 to 10 kg.
