Can Ai Kang 58 wheat be used in Jining?

Ai Kang 58 wheat seeds can be used in Jining, and are widely suitable for planting in Hebei, south of Jinan, Shandong, Xiangyang, Hubei (formerly Xiangfan), south of Shaanxi, Henan, Anhui, Jiangsu, Hebei, Shandong, Hubei and north of Huaiyuan, Anhui.

Suitable for early sowing and close planting

Bainong Ai Kang 58 is a semi-winter dwarf multi-spike variety with strong cold resistance. Early sowing and close planting are suitable at the end of September. The results of sowing date test showed that the yield of Bainong Ai Kang 58 did not change much before sowing 65438+1October 30, and the yield was the highest when sowing 65438+1October. After 10 year 10 30, the sowing yield decreased obviously. From the perspective of high yield, 65438+1mid-October is the best sowing date, and 65438+ 10 is the best sowing date.

The experiment of sowing quantity showed that the sowing quantity of Bainong Ai Kang 58 was elastic, and the effect of different sowing quantity on yield was not obvious. The yield of basic seedlings per mu is between1.4000 ~ 2 1 10000, and the number of tillers and ears is basically the same, and the yield per mu is between 49 1 ~ 505 kg. This shows that Bainong Ai Kang 58 has strong self-regulation ability, and different basic seedlings can obtain higher yield. But when the yield of basic seedlings is 200 thousand per mu, the yield is the highest; When the yield of basic seedlings per mu is 654.38+ 10,000, the number of spikes per mu is the least, the number of grains per spike is more, and the yield is the lowest. With the increase of sowing amount, the number of basic seedlings and panicles per mu increased correspondingly, but the number of grains per panicle decreased. Therefore, for the yield level above 500 kg per mu, 1.5 ~ 0.2 million/mu is the suitable sowing amount, and 1.8 ~ 0.2 million/mu is the best. At the same time, the uniformity of wheat seedlings should be checked after emergence, and germination and replanting should be carried out in time.

Suitable for high school fertilizer field planting.

Bainong Ai Kang 58 has a lower plant height and is more suitable for planting in high and medium fertilizer fields. More seed fertilizer and proper topdressing are the basis of high yield. Fertilization experiment (pure nitrogen content is set at 0, 4, 8, 12, 16, 20, 24, 28, 32kg/ mu, and fertilization at jointing stage and heading stage is 70% and 30% respectively) shows that with the increase of nitrogen application rate, the yield is also increasing. When the amount of nitrogen fertilizer is 20-28 kg/mu, its yield is obviously higher than other different fertility levels. Fertilization experiment showed that the suitable nitrogen fertilizer dosage for planting Bainong Ai Kang 58 was 20 ~ 28kg/mu. At the same time, after winter irrigation in June 5438+February, it is necessary to hoe in time to break the hardening and loosen the soil to preserve moisture; At the same time, it is necessary to water the water that turns green, saves water and heads and blooms.

Pay attention to pest control

Bainong Ai Kang 58 is highly resistant to stripe rust, stem rust and powdery mildew. The focus of pest control is aphids, leaf rust and scab. Spraying omethoate or other chemicals to control aphids before and after heading, and spraying triadimefon to control leaf rust and scab at filling stage.
