Taixing Sweet Peanut is a peanut product that is produced through the appropriate delay of sowing date and harvesting period during the peanut cultivation process. After quality analysis, the water soluble total sugar content was significantly increased, and the quality of food was significantly improved. Since 2000, we have conducted trials and demonstrations on the planting period, density, fertilizer management, prevention and control of diseases and weeds in Taixing sweet peanuts, and accumulated a large amount of data to form a preliminary cultivation technology system for Taixing sweet peanuts. And standardized production and demonstration around the system. In 2003, 1.87 hectares of demonstrations in Nanyin Village of Taixing Town were planted on July 18th and harvested on October 27-30. The average fruit yield was 7252.5kg (3,771kg dried fruits) per hectare, the fresh fruit unit price was 2.2 yuan/kg, and the output value per hectare reached 1,5955.5. yuan. A large area of ​​autumn peanuts produced 3,750 kilograms of dried fruit per hectare and a breakthrough of 15,000 yuan in fresh fruit production. Have achieved ideal social and economic benefits. The main technical measures of Taixing sweet peanut are introduced as follows: 1 Select high-quality, early-maturing, medium and small fruit varieties. After the fall, peanuts should be used in medium and late-maturing medium- and small-grained varieties. They should also have the characteristics of moisture resistance and disease resistance, so as to adapt to the high temperature, high rainfall and the emergence of seedlings, diseases, insects and waterlogging. Variety tests showed that Taihua No. 4, Taihua No. 1 and Taihua No. 2 which were selected for the selection of Taixing Agricultural Sciences were most suitable. 2 Do seed treatment to prevent diseases and pests. During the whole life of autumn peanuts, the pests and diseases are lighter. Through seed treatment, the ideal preventive effect can be achieved. The method is based on 1-2 days of tanned seeds on the basis of shelling, and then each hectare with 25% wettable carbendazim powder 750g, 40% phoxim EC 15ml, ABT6 rooting powder 0.45g, even after 30kg watered Seed dressing. After mixing, broadcast, with the broadcast with the mix. 3, formula fertilization, reasonable close planting, before the appropriate sowing dates after harvesting full-scale spread of manure ash 22500-30000 kg of manure, ternary compound fertilizer 600-750 kg (N, P2O5, K2O content ≥ 48%) / hm2. The application methods are: organic fertilizer combined with deep plowing and full-layer application. Chemical fertilizers are concentrated and applied to the ridge bottom as basal fertilizer when ridged. After the seedlings are used, the seedlings are topped in 5 days, and 5 urea water is used to irrigate the roots; 10 days after flowering. Spray plant growth promoters such as Jinbang No. 1 (450g/hm2) at intervals of one week and spray twice. After autumn, peanuts have sufficient light in the middle and late stages of growth, the temperature is relatively low, and the number of pods per plant is relatively small. Therefore, the population density must be increased to increase the yield. The experiment shows that the appropriate density of peanuts after the late autumn is 330,000 plants/plant. Hm2 (22,000 plants/mu). Regulate the sensation and sow the crops. In order to balance production and quality (especially sugar content), sowing is better on July 12-15, and no later than July 20. At the same time, attention should be paid to adjusting the humidity in the field to ensure that the soil moisture is the maximum amount of water in the field. %-70%. 4 Ridge cultivation, double membrane covering double membrane covering is the key measure for peanut cultivation in late autumn. In order to achieve a certain growth period after the fall of the frost, peanuts must be leveled and used as an afforestation. The specifications for the lifting are: width 70-72cm, width 45-50cm, height 15-20cm. After removing the ridge, the film is removed (first pass) and sowed. The first film thickness is 0.006mm. In the second half of October (before the first low temperature or before the frost), two films (film thickness 0.012mm) were directly covered and compacted. 5 appropriate control to prevent prosperous growth. Appropriate sowing of autumn peanuts, rapid growth at seedling stage, a large amount of growth, the performance of the trend of the field, can be up to 30cm when the strain, mu with 15% wettable paclobutrazol powder 20-30g appropriate control to avoid prosperous Long lodging. 6 timely harvest, high-yield and high-efficiency fall-delayed peanuts within a certain range, the water-soluble total sugar content increased with the delay of harvest; but the harvest was too late, rotten fruit increased, affecting quality. Therefore, it is generally appropriate to harvest locally before and after November 15.
