一、苗期开花、开杈、结籽的情况1958年,荚头麻苗期开花比较普遍,上虞县全县有4,050亩荚头麻在不同程度上出现苗期开花现象。如原娥江乡后郭社赵家第7小队3月28日播种的0.05亩温床育苗荚头麻,苗期开花植株达100%;4月7日种的1.1亩荚头麻,苗期开花植株达88%;4月18日种的5亩荚头麻,苗期开花占38%。苗期开花的麻株一般在苗高3寸时就已现蕾,4寸起开花。如赵家村在4月18日种的1.1亩荚头麻,6月3日苗高3.5—5寸,现蕾开花的植株占62%(其中现蕾而尚未开花者占50%);6月5日苗高5.5—8寸,现蕾与开花占88%(开花占21%);6月10日,苗高8寸以上,开花占88%(即原67%现蕾的已全部开花)。
First, the seedling flowering, open twigs, seed the situation In 1958, the seedling stage numbheads flowering is more common in Shangyu County, the county has 4,050 acres of pod head Ma appears to varying degrees, the phenomenon of flowering at seedling stage. Such as the original E River Township Guo Guo Zhao team 7th March 28th sowing of 0.05 acres of hotbed seedlings nursery head numb, seedlings flowering plants up to 100%; April 7 species of 1.1 acres of pod head Ma, seedling flowering Up to 88% of the plants; April 5 April 5 acres of pod head Ma, seedling flowering accounted for 38%. Seedling blossoming nursery generally 3 inches in height when it has bud, 4-inch from the flowering. Such as Zhao Jiacun on April 18 planted 1.1 acres of pod head Ma, June 3 seedlings 3.5-5 inches tall, flowering plants accounted for 62% (of which budding yet not flowering accounted for 50%); June On the 5th, seedling height 5.5-8 inches, budding and flowering accounted for 88% (flowering accounted for 21%); June 10, seedling height 8 inches above, flowering accounted for 88% (that is, the original 67% of the bud has been fully flowering) .
