不 同密度试 验结果表 明，宁杂 １ 号在亩 施２０ ｋｇ 左 右纯氮， 亩栽０ ．３ ～０ ．５ 万株 的稀 植栽培条件 下，一次 有效分枝 可达１３ ～１６ 个，二 次有 效分 枝 ２０ ～２６ 个 ，亩 总角 数３ ８０ ～４００ 万 个， 亩产可达２００ ｋｇ 左右。 宁杂１ 号 稀植栽培 每亩可节 省用工 投入约３ ０ 元，比常 规密度净 增产 值近 ８０ 元，经济效 益显著 。
The results of different density test showed that Ningza 1 is about 20 kg of pure nitrogen in mu, with 0 mu per mu. 3 ~ 0. Under the condition of sparse planting of 50000 plants, the number of effective branches can reach 13 ~ 16, the effective branches of secondary branches are 20 ~ 26, the total number of mu is 30 ~ 40 million, and the yield per mu is about 200 kg. Ning miscellaneous rare planting on the 1st per mu can save labor input about 3 0 yuan, net output than the conventional density of nearly 80 yuan, significant economic benefits.
