1985～1986年,在溧水县傅家边大队两个自然村的3种土壤(黄砂土、黄白土及鳝血白土)上移栽了4.346亩低芥酸油菜宁油八号。三种土壤耕作层(0～15cm,下同)含热水溶性B相应为0.17,0.18及0.29ppm.在主要施用NPK化肥的基础上,每亩施含水溶性B11.3％的硼砂0.5kg,均开花结实,共收菜籽490kg,平均亩产112.75kg。而其他农户种植的宁油八号出现不同程度的花而不实。同年,江苏省宁镇丘陵地区的溧水、句容、溧阳、高淳、江宁等县种植的宁油八号也出现了不同程度的花而不实。为进一步验证本试验结果,1986～1987年在
From 1985 to 1986, 4.346 mu of low-erucic acid rape Ningyou 8 was transplanted on three kinds of soils (yellow sand soil, yellow-white soil and eel blood white soil) of two natural villages in Fujiabian Fighting Area, Lishui County. Three kinds of soil tillage (0 ~ 15cm, the same below) with hot water soluble B corresponding to 0.17,0.18 and 0.29ppm. In the main application of NPK fertilizer based on the application of water-soluble B11.3% per acre borax 0.5kg, Are strong flowering, a total of 490kg received seed, the average yield 112.75kg. However, Ningyou 8, which is planted by other farmers, has flowers of varying degrees rather than real ones. In the same year, Ningyou 8, which was planted in Lishui, Jurong, Liyang, Gaochun and Jiangning counties in the hilly area of Ningzhen, Jiangsu Province, also witnessed varying degrees of fragmentation. In order to further verify the test results, from 1986 to 1987 in
