早熟黑穗醋栗蕾、花期营养特性的研究

Studies on Nutrition Quality of Earty B1ack-Tasseled Gooseberry at Flower Bud and Florescence States

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％。
