Study on Cultivation Techniques with High Yield of High-quality Super Rice Longjing 21 in Cold Region
摘要
Abstract
In order to give full play to the huge yield potential of super rice varieties ,taking super rice variety Longjing 21 as material ,its different sowing time ,sowing amount ,planting density and fertilization amount were studied ,and the high-efficient and high-yield cultivation techniques was assembled and integrated by the combination of superior rice varieties with superior method .The results showed that the suitable sowing date of Longjing 21 was from 15 to 20 in April ,the best sowing amount was 200~250 g·m-2 ,the most appropriate planting density was 25 hole·m-2 ,planting specification was 30 .0 cm × 13 .3 cm ,5 strains per hole ,the best fer-tilizer amount for pure N ,P2 O5 and K2 O were 130 ,65 and 65 kg·hm-2 respectively ,the yield could up to 9 t·hm-2 .关键词
