春小麦“互助红”是我县主栽作物之一,1981年全省种植面积达50余万亩,仅次于“阿勃”居第二位。“互助红”在我县自然条件下,苗期生长缓慢,耐干寒瘠薄、分蘖力强、成穗率高,根重、茎长、叶茂,后期耐冻和阴湿,抗病,口紧不易遭雹落粒。种子休眠期长,灌浆期较慢,千粒重稳定,是其稳产的主要因素。该品种宜在海拔2500—2700米的旱地、高位水地种植。出苗至成熟需≥0℃积温1500—1700℃;灌浆期适宜温度为15—17℃;3—10月份平均气温在9℃左右,湿润系数0.76—1.32。适于早播,施足基肥,重施磷肥,中施氮肥,氮磷比为1∶1;种植密度:旱地每亩保苗20—25万,水地为25—30万,为其栽培的主要技术措施。“互助红”在我县种植面积较大,据1981年初步统计约23.1万亩,占小麦播种面积的61.4％,其它大通、湟中、平安和化隆等地也有种植,全省累计面积50余万亩,仅次于“阿勃”。“互助红”是在1964年我县双树公社大通苑二队农科组,从引进的小麦品系中选出来的(原名不详),因外部形态为顶芒、红穗,丰产性似于“阿勃”,故群众称为“红阿勃”、“火麦”。1975年开始在全县大面积种植,1979年被县审定为春小麦良种,1980年经省有关技术部门鉴定名为“互助红”春小麦品种。
Spring wheat “mutual aid red” is one of the main crops in our county. In 1981, the planting area in the province reached more than 50 million mu, second only to “Arbor”. Under the natural conditions of our county, “mutual aid red” grows slowly at seedling stage, is resistant to dry barley, has strong tillering ability, high ear percentage, root weight, stem length, leafiness, resistance to freezing and dampness in the later period, disease resistance, Tight hard to be hail off granule. Seed dormancy long period of filling is slow, 1000 grain weight is stable, is its main factor of stable production. The variety should be at an altitude of 2,500-2700 meters of dry land, high water cultivation. The seedling emergence temperature should be 1500-1700 ℃ when the temperature is up to 0 ℃. The optimum temperature is 15-17 ℃ during the filling stage. The average temperature is about 9 ℃ from March to October and the wetting coefficient is 0.76-1.32. Suitable for early sowing, applying enough basal fertilizer, re-application of phosphate fertilizer, medium nitrogen fertilizer, nitrogen and phosphorus ratio of 1: 1; planting density: 20-25 million acres of seedlings per acre in dry land, water is 25-30 million for the cultivation of the main Technical measures According to preliminary statistics in 1981, about 231,000 mu was occupied, accounting for 61.4% of the sown area of wheat. Other Chase, Langzhong, Heping and Hualong areas were also planted. The total area of the province was 50 More than 10,000 mu, second only to “Ah Bo.” “Mutual aid red” was selected from the imported wheat strains (formerly unknown) by the Agricultural Science Team of the Second Team of Datongyuan Court in Shuangshu Commune in 1964. Because of the external shape of Top Mountain, Red Spike and high yield, Bo “, so the masses called” red abalone “,” fire wheat. “ Since 1975, it has been planted in a large area in the county. In 1979, it was approved as a spring wheat by the county. In 1980, it was appraised by the relevant technical department of the province as ”mutual aid red" spring wheat varieties.
