不同播种量对果蔗产量和品质影响的研究
Report on the Effect of Different Seeding Rate to Yield and Quality of Garden Cane
摘要
Abstract
Seeding rate of 270000 buds/hm2 would cause somewhat negative effect to emergence rate, but bring about outstanding increase in the number of seedling and tillering. There would be much increase in stalk height, stalk diameter, stalk weight and millable stalks. As a result, the yield would increase outstandingly with the best benefit and the least costs. It would present good commercial and technical traits and no negative effect to resistance of adversity and therefore it would be the best choice for seeding rate. Seeding rate of 360000 buds/hm2 would cause somewhat negative effect to both emergency rate and tillering rate, but it would bring about outstanding increase in the number of seedling and tillering. Obvious increase in stalk height would be obtained. Increase in stalk diameter ranked second. Stalk weight, millable stalk and cane yield increased considerably. It would present good commercial and technical traits and no negative effect to resistance of adversity. The cost, increase in cane yield per unit cost and benefit also ranked second and therefore it would be a secondary choice for seeding rate. Seeding rate of 450000 buds/hm2 would cause somewhat negative effect to both emergency rate and tillering rate, but the number of seedling and the number of tillering were almost doubled compared with the check. There would be obvious increase in stalk height, and the stalk diameter ranked third. Stalk weight and cane yield increased considerably. It would present good commercial and technical traits and no negative effect to resistance of adversity. Its cost was the highest, the increase in cane yield per unit cost and benefit ranked third, therefore this seeding rate would only be applied when using cane tops for seeds. It is not recommended when whole stalks were used for seeds.关键词
