“竹科二号”是舟山地区农科所于1972年用竹莲矮与科矮13杂交,1975年定型。三年来试验试种结果表明竹科二号是一个多穗、大粒、出米率高、米质好、抗稻瘟病能力较强、产量高的品种。1976年全区推广面积约一万亩,1978年将继续扩大推广。产量表现经过连续三年来的比较试验,竹科二号平均亩产942.6斤,比广陆矮四号平均亩产877.6斤,平均增产7.4%,增产幅度为5.4～9.4%,1976年地区13个点联合试验,结果有12个点增产,平均亩产947.9斤,比广陆矮四号平均亩产879.1斤,平均增产7.8%,各地试种结果, “Bamboo Branch II” is the Zhoushan Agricultural Science Institute in 1972 with bamboo Lian short and Branch 13 short hybridization, stereotypes in 1975. Three years of trial test results show that bamboo Branch II is a more spike, big grain, rice rate is high, good quality rice, blast resistant ability, high yield varieties. In 1976 the area to promote an area of ​​about 10000 acres, 1978 will continue to expand promotion. Production performance After three consecutive years of comparative tests, bamboo average yield of 942.6 kg No. 2, compared with an average of 877.6 kg per square Uygur Autonomous Region, an average yield of 7.4%, an increase of 5.4% to 9.4% in 1976, 13 Point joint test, the results of 12 points yield, the average yield of 947.9 kg, compared with the average Guanglu Dwarf No. 879.1 kg, an average yield of 7.8%, the test results around,
