对早熟黑穗醋栗二个品种蕾、花期干物质和主要营养元素的吸收、积累和分配规律进行了研究。结果表明,早熟黑穗醋栗品种蕾、花期生育进程的二个阶段,其干物质和营养元素的吸收、积累和分配不同,但基本规律一致。蕾期阶段干物质积累幅度15.48％～24.35％。花期阶段干物质积累幅度初花期为4.5％～5.2％。盛花期为50.08％～57.33％,末花期为20.70％～21.99％。从N、P、K的吸收、积累和分配幅度,蕾期阶段分别为27.33％～32.40％、23.37％～25.25％、17.25％～21.29％;花期阶段的初花期分别为23.77％～30.60％、25.52％～27.51％、23.57％～28.37％;盛花期分别为10.52％～20.43％、20.92％～24.26％、23.65％～28.63％;末花期分别为23.40％～34.03％、24.85％～28.03％、25.73％～31.48％。
The regulation of absorption, accumulation and distribution of buds, anthesis dry matter and main nutrient elements of two cultivars of early currant black currant were studied. The results showed that the absorption and accumulation of dry matter and nutrients were different in the stages of bud and flowering stage of early maturing black currant, but the basic laws were the same. The dry matter accumulation in bud stage was 15.48% ~ 24.35%. Flowering stage dry matter accumulation rate of flowering of 4.5% to 5.2%. Full flowering of 50.08% ~ 57.33%, the end of flowering was 20.70% ~ 21.99%. The initial stage of flowering stage was from 23.77% to 30.60% for the stages of absorption, accumulation and distribution of N, P and K, respectively, from 27.33% to 32.40%, from 23.37% to 25.25% and from 17.25% to 21.29% 25.52% -27.51% and 23.57% -28.37% respectively. The flowering periods were 10.52% -20.43%, 20.92% -24.26% and 23.65% -28.63%, respectively. The flowering periods were 23.40% -34.03% and 24.85% -28.03% respectively. 25.73% ~ 31.48%.
