1.选穗首先要确定好需要提纯复壮的品种,在该品种成熟收获之前,到种子田或者大田里,选摘具有该品种特征特性、生长一致、抗病性好的单穗若干个(一般1亩穗行需要选摘单穗3000个)。摘取下来的单穗晾晒以后,分穗脱粒,一个穗子上的种子装在一个小纸袋里。脱粒时注意淘汰混杂和变异的穗子(例如白粒品种中出现的红粒穗子),并淘汰子粒不良的穗子,脱粒后要认真晾晒,妥善保管。 2.穗行种植 (1)选地:①地力要十分均匀,以便于比较穗行好坏。②土壤肥力要高,但不要超过品种的抗
1. Select the ear first to determine the need to purify and rejuvenate the variety before the variety mature harvest, to the seed field or field, select the characteristics and characteristics of the breed, growth consistent, good resistance to a number of single panicle (generally 1 acre ear need to pick a single spike 3000). After the single spike which is taken out is dried, the spikelets are threshed, and the seeds on one spikelet are put in a small paper bag. When threshing, be careful to eliminate the mixed and mutated ears (such as white grains appear in the red ears), and out of the bad ears of grain, threshing should be carefully drying, safekeeping. 2. Spike row planting (1) selected: ① ground force should be very uniform, in order to compare the ear good or bad. ② soil fertility should be high, but not more than the variety of resistance
