Yimai No. 1

Yimai No. 1 was bred by using 1029 as female parent and super large panicle 84 (79) as your cross.

First, the main characteristics. 1) Dwarf and sturdy: generally, the plant height is only about 70 cm, and the plant is stout; the root system is well developed and is specially resistant to lodging. 2) the spike shape is unique: the spike is corrugated, the top is large and the bottom is small; generally, the length of the spike is more than 12 cm, the length is more than 15 cm, there are 20 spikelets per spikelet, 3 spikelets per spikelet, and more than 12 spikelets in the upper spikelet, up to 16; the arrangement of spikelets is extremely compact, with more than 120 spikelets per spike, up to 140 grains at most, and the number of grains per spike is 2 times higher than that of ordinary varieties. Ear head more and more up and down, different, especially attracted to love. 3) strong tillering ability and even growth: 14 tillers per plant, up to 28 tillers. The plant grows fast and has good uniformity. The wheat feet are sharp and the ears are large and even. Mature ear layer like a knife cut in general, neat, dense, excellent growth, see no praise, welcomed by the broad masses of farmers. 4) High yield and high quality: according to my arrangement for many years, the yield per mu is more than 600kg and 700kg. The planting in many places is 150-250 kg higher than that of the main local varieties. The grain of this variety is white, the weight of a thousand grains is about 45 grams, the protein content is as high as 15.35%, and the flour yield is 87%. The tendons are delicious and belong to a high-quality variety. 5) it is resistant to late sowing and is suitable for both winter and spring: although this variety is semi-winter, it is suitable for sowing in a wide range. According to the spring sowing experiment of northern spring wheat and our land, whether it is sowing in October or after the beginning of spring in the following year, it can mature normally. Therefore, this variety can not only be sown in autumn and winter in Huang-Huai-Hai region, but also planted in the northern spring wheat area, and can be planted in a large area in the middle and lower reaches of the Yangtze River.

Second, main points of cultivation. 1) applying 5 tons of high-quality mature organic fertilizer, 100 kg ammonium bicarbonate, 100 kg calcium superphosphate, 20 kg potassium sulfate and 1.5 kg zinc sulfate per mu; 2) sowing from October 5 to 15. 4kg per mu of seeds used in Huang-Huai-Hai and northern spring wheat areas, and 8kg per mu of rice fields in the middle and lower reaches of the Yangtze River. It is suitable to plant 22 ~ 250000 plants per mu. 3) higher yield can be obtained by spraying with potassium dihydrogen phosphate combined with urea or Gaomeshi for 5 times from March to May after the beginning of spring.
