硬粒种子在豆科作物申最为常见,尤以小粒豆科作物——紫云英种子更为突出,严重影响种子发芽率,给生产带来一定困难。因此,解除紫云英硬粒种子技术,提高种子发芽率,在大面积绿肥生产中就更加迫切了。我于一九八二年五月紫云英种子收获七天后,用八种不同的处理方法(见下表),经反复对比试验,选出四种有效解除硬粒的方法:一、砂纸对擦法:采用工业用粒度60No 砂纸,将二片砂纸分别装钉在两块木板上,把五克重种子放入两块木板之间,上块木板加压到一公斤重,转旋上块木板对擦三分钟。
Hard seed seeds are the most common in leguminous crops, especially small leguminous crops - aspen seed more prominent, seriously affecting the seed germination rate, to bring some difficulties. Therefore, lifting the technology of hardwood seed Astragalus to improve seed germination rate, in a large area of green manure production even more urgent. Seven days after harvesting the seeds of Chinese milk vetch in May 1982, I used eight different treatment methods (see the table below) to compare four different methods to effectively remove the hard particles: Rub method: the use of industrial size 60No sandpaper, the two sandpaper were nailed to the two boards, five grams of heavy seeds into the two boards, the pressure on the board to a kilogram of weight, turn spin on the block Wood board rub for three minutes.
