1959年,我连利用262亩糖用甜菜的块根进行了原地越冬的生产性试验。这些地是在5月2日播种的。品种为B_(00)与B_(00)。封冻前单株甜菜块根重,B_(020)品种地为30—120克,极少露出地面,单株叶数8—20片;B_(030)品种地为250—1500克,块根有1/3—2/3的长度露出地面,这种地用马粪、腐殖质、草木灰等,对块根进行了覆盖。当地(石河子地区)冬季积雪最厚达32厘米,冻土最深达57厘米。1960年4月20日春栽母根作为对照。两者的生长发育及产量情况列入表1及表2。
In 1959, I even used 262 acres of sugar beet root tuber for in-place winter production test. These are sown on May 2. Varieties B_ (00) and B_ (00). Before thawing, the root weight of individual beet tubers was 30-120 g for B 020 varieties, with few leaves on the ground, 8-20 leaves per plant; 250-1500 g for B 030 varieties and 1 / 3-2 / 3 of the length of the exposed ground, this use of horse manure, humus, ash, etc., covered the roots. The local (Shihezi region) winter snow thickness of up to 32 cm, the deepest permafrost of 57 cm. April 20, 1960 spring planting root as a control. The growth and yield of both are listed in Table 1 and Table 2.
