Suinong 14 (soybean)

This variety is a new mid-maturing spring soybean variety bred by Suihua Institute of Agricultural Sciences, Heilongjiang Academy of Agricultural Sciences, using Hefeng 25 / Suinong 8 as material.

The growth days of Suinong 14 were about 120 days, and the active accumulated temperature was about 2486 ℃. Sub-limited podding habits, high and high plants, few branches, dense pods on the main stem, purple flowers, long leaves, thick green leaves, gray hairs. The internodes are short, the pods are dense, and there are more than 3 or 4 grains. The seed is round, the seed coat is bright yellow, the navel is colorless, and the weight of 100 seeds is 21g to 22g. The protein content is 41.72% and the fat content is 20.48%. Mild diseases and insect pests, moderate resistance to gray leaf spot, disease grain rate is only 1.69%, heart-eating insect rate 2.5%, strong stalk, like fertilizer and water, wide adaptability.

The results of the appraisal test of this variety in the institute from 1991 to 1992 showed that the average yield per mu was 230.4 kg, which was 17.4% higher than that of Hefeng 25, which was 17.4% higher than that of Hefeng 25, which was higher than that of Hefeng 25 in Heilongjiang Province. the average yield per mu was 161.9 kg, 12.3% higher than that of Hefeng 25, and the average yield per mu was 157.1 kg, 11.4% higher than that of Hefeng 25. In 1996, the yield per mu was 173.3-200kg, and in 1997, the highest yield per mu was 285kg.

Cultivator Suihua Institute of Agricultural Sciences, Heilongjiang Academy of Agricultural Sciences

Regional and technical Suinong 14 is suitable for popularizing and planting in the northern spring bean areas such as the upper limit of the second accumulated temperate zone and the third accumulated temperate zone and the lower limit of the first accumulated temperate zone in Heilongjiang Province. at present, it has been extended to Jilin, Inner Mongolia, Liaoning and other areas, with a total extension area of 5.64 million mu, creating economic benefits of 210 million yuan. It is estimated that the maximum annual extension area can reach 7 million mu.

Cultivation rules:

1. The suitable soil should avoid continuous cropping as far as possible, and the first stubble is mainly corn, miscellaneous grains and potatoes. Implement the autumn deep turning of 20cm to 30cm, then flatten the thickness and form a good ridge. When the soil is thoroughly 10 cm in the spring of next year, it should be suppressed again with a ballast to avoid running away the soil moisture.

two。 Seed treatment selected seeds, purity of more than 98%, purity of more than 98%, bud rate of more than 90%, seed coating to control underground pests.

3. Sowing date May 1-5 daily precision seeding machine sowing, 60-70 cm large ridge, double precision-on-demand on the ridge, or 45-50 cm small ridge "belt" precision-on-demand.

4. Fertilizer and water management deep application of seed fertilizer, 10 kg of diammonium phosphate per mu, 5 kg of urea, 5 kg of potassium sulfate, 3 cm and 5 cm of seed. In areas with favorable conditions, proper irrigation can be made during flowering, pod setting and grain filling stage to improve pod setting rate and fullness of seed filling.

5. Disease and pest control red spiders and thrips were sprayed in the field with 40% omethoate 400 times or 500 times of omethoate or acaricide. Before the appearance of the soybean heart borer Efeng in the first and middle of August, the soybean heart borer was fumigated with 80% dichlorvos or sprayed with 2.5% pyrethroid pesticides to control the soybean heart borer.
