从1985年起,我们采用塑料中拱棚覆盖制杂交种子,不仅产种量高,且成本较低,便于推广,取得了很好的效果。3年累计在岐山县岐星点制种34亩,总产种子284公斤,平均亩产种子8.4公斤,较露地亩产5.1公斤增产64.7%,最高亩产达13.9公斤,每亩纯收入1500元以上。具体作法是: 1.培育壮苗。壮苗是丰产的基础。根据早丰母本的生育期及我地气候特点,育苗可在温室或阳畦内进行。适宜播种期是2月中旬,父本较母本早播15～20天。播种至出苗要求温度28～32℃,出苗后降至22～25℃。出苗后30天左右分苗于营养纸钵。分苗前对幼苗进行降温锻炼,分苗后保持28℃
From 1985 onwards, we used the plastic covered shed to cover the hybrid seed, which not only produced high yield, but also low cost, easy to popularize and achieved good results. In the past three years, the plant has 34 mu of total output of 284 kilograms of quinoa seeds in Qishan County, with an average yield of 8.4 kg per mu, 5.18 kg more mu yield and 64.7 percent mu yield than the open land, with the highest mu yield of 13.9 kilograms and a net income of 1,500 yuan the above. Specific practices are: 1. Cultivate strong seedlings. Strong seedling is the basis of high yield. According to the mother of the early abundance of fertility and climate characteristics of my life, nursery can be carried out in the greenhouse or yangliu. Suitable sowing period is in mid-February, the male parent sow earlier than the mother 15 to 20 days. Sowing to the emergence of temperature requirements of 28 ~ 32 ℃, after emergence dropped to 22 ~ 25 ℃. About 30 days after emergence of seedlings in nutrition bowl. Seedlings before the seedling for cooling exercise, sub-seedlings to maintain 28 ℃
