1.选好留种地。留种地切忌重茬,以选用有灌溉条件的水旱轮作地最为适宜,这种地块选留的花生种子,生活力较强,播种后有利于全苗、壮苗。 2.严格进行收获前的三选。①评选:在田间观察的基础上,收获前再一次逐行逐畦认真地检查,选用植株整齐一致、没有病虫害的畦,划定为选种留种地,并从严拔除混杂的品种和有病虫害的植株。②株选:根据本品种的形态特征,收获时要选分枝多、节间短、结荚多而集中、成熟齐的优良单株作种株。种株一是不能用水选,果荚上带的上要晒干后让其自然脱落;二是先整株悬挂阴干,经2～3天后才脱荚。这样可使植株和果菜的一些养分转运到种子中去,提高种子的发芽力。脱荚前再
1. Choose a good place to stay. Avoid cropping stubble to choose the best conditions for irrigating dry and round place, the selection of peanut seeds in this plot, strong vitality, sowing is conducive to the whole seedlings, strong seedlings. 2. Strictly before the harvest of the three elections. ① Selection: On the basis of field observation, before the harvest, they should be checked line by line and carefully, and the plants that are neat and unanimous and free of pests and diseases should be selected as the place for seed selection and the mixed varieties should be severely removed Plant diseases and insect pests. ② strain selection: According to the morphological characteristics of the species, when harvesting to choose more branches, internodes short, pod and more concentrated and mature homogeneous Qi as a single plant strains. First, the strain can not use water, the pod on the belt to dry after let it fall off naturally; Second, the whole plant hanging dry, after 2 to 3 days before taking off the pod. This allows some of the nutrients in plants and fruits and vegetables to be transported to the seeds to improve seed germination. Before podding again
