II. Output performance: In 2001, the regional trials in Henan Province, the yield of seed cotton, lint, and pre-frost lint were respectively increased by 26.7%, 28.4%, and 28.8% compared with the control; in the production test in 2002, the yield of seed cotton, lint, and frost lint was respectively increased. Compared with the control, the cotton 41 increased production by 11.8%, 9.19%, and 8.9%. In 2003, it continued to participate in the production test. Seed cotton, lint, and pre-frost lint yielded 17.4%, 17.5%, and 14.9% higher than the control, respectively. In the same year, they participated in the spring cotton resistance of Hebei Province. In the regional trials, seed cotton, pre-frost seed cotton, and lint cotton were increased by 7.1%, 8.2%, and 13.5%, respectively, compared with the control 33B.
3. Disease resistance and insect resistance: The identification results of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences are varieties with resistance to wilt and resistance to Verticillium wilt. The second-generation H. armigera decreased the rate of 87.01%, and the survival rate of third-generation larvae of third-instar larvae was 10.67%. The comprehensive assessment of the resistance level was grade 2.
Fourth, the quality analysis results: 2001,2002 by the Ministry of Agriculture Cotton Quality Supervision and Inspection Center unified test results, two years average cashmere length 30.5mm, uniform 85.4%, strong ratio 30.7CN/tex elongation 6.2, micronaire value 4.6, Reflectance 76.9, yellowness 7.8, spinning uniformity index 150.
V. Cultivation and management techniques: This variety is suitable for planting in the cotton fields of the Yellow River Basin. It has good precocity, a wide range of suitable scope, and a suitable sowing period. It is not only suitable for film-mulching, seedling transplanting, but also suitable for spring planting, intercropping and other planting forms. In terms of cultivation and management, according to its fertility characteristics, we must grasp the following key measures:
1. According to the characteristics of rapid development and concentration of bells, the principle of increasing basic fertilizer, applying early flowering boll-fertilizer, and applying top dressing fertilizer should be adhered to. High-yielding plots should generally be applied at the end of 2-3 m of organic fertilizer, 20 kg of diammonium, 20 kg of potassium fertilizer, 10 kg of urea, 0.5-1 kg of zinc fertilizer, and 0.5 kg of boron fertilizer. Drought should be watered in time for the whole growing season until mid-September. Watering after boll opening can effectively increase the boll weight. The late spraying foliar fertilizer is an effective measure to prevent premature senescence, increase the boll weight, and prevent the falling off of the upper bud bell. Generally, in early August, 2% urea solution or 2% high-quality potassium sulfate solution is sprayed on the defertilizer cotton field. Spray every 7-10 days and spray three times. 2. Take comprehensive measures to control excessive pandas to prevent premature aging. Since Xinkang 4 has the characteristics of budding early, rapid development, and concentrated bolls, if the cultivation and management are not properly performed, it is easy to form too many prunes. Therefore, we should pay attention to the cultivation and management: (1) sowing should not be too early, appropriate sowing in the best sowing time in the local area, appropriate postponement of nursery and transplanting time, promotion of intercropping and local direct seeding and other cultivation methods according to local conditions; (2) Due to early sowing, budding earlier cotton fields should adopt the method of early buds to control excessive fusota; the ideal Chengling structure consists of 5% peach, 80% peach, and 15% peach. ; go to early buds are generally carried out in late June, the number of buds due to budding cotton field sooner or later may be appropriate, usually 4-8 per plant is appropriate, to bud site control in the lower 4 fruit branches, in order to save labor can also remove the lower part 2-3 fruit branches; (3) promotion of simplified pruning techniques, leave 2-3 leaf branches below the fruit branch, also have a certain effect on preventing excessive prunes. 3. Reasonably dense planting. Xinkang No. 4 has the characteristics of less leaves, strong bells, and less madness. Suitable for simplifying pruning cultivation, simplifying pruning cultivation should be appropriate sparse, leaving the density of seedlings to local habits, generally less than the conventional pruning acres left 20-30% reduction. The conventional pruning cultivation is determined by the fertility. In the northern cotton area, 3000-3500 strains of low-water fertilization land are reserved; 2,500 water fertilizer areas are cultivated; 2000-2500 strains of high-water fertilization area are reserved. 4. A small number of times, full control. Xin Kang 4 growth is relatively stable, and control should be based on local conditions, a small number of times and look at the days, see the land, see the principle of the seedlings. Generally, the amount of acre is reduced, 0.3-0.5 grams for budding period, 1-2 grams for early flowering period, 2-3 grams for flowering period, and 3-5 grams for 7-10 days after topping. To meet the national standards of shrinking security, the active ingredient content of more than 96%, the impurity content of 1.5% or less, such as "Yinhua card" contract Jie security. 5. Pest control. Xinkang No. 4 has strong resistance to wilt and resistance to Verticillium wilt, but the severely diseased plots should strengthen the control of seedling stage diseases. The second-generation cotton bollworm generally does not use chemical control, and it is sprayed and controlled at the peak of egg laying in the year of major occurrence; third and fourth-generation cotton bollworms are treated with light and heavy spraying. The non-Lepidoptera pests such as cotton aphid and blind locust should be promptly controlled.
Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
