In this paper,the writer discusses four factors which affect the rice yield significantly,i.e.the leaf age in transplantation,row distance.fertilizer application of tilling stage and panicle initiation stage with the tetravariate qaudratic orthogonal rotating combining design during three years.The results from the study indicate that the optimum value of the four factors above for high yield is 4.9~6.0,29.7~34.3cm,11.9~16.8kg/hm2,6.0kg/hm2 respectively.

采用四元二次正交旋转组合设计,从对当地水稻生产影响较大的移栽叶龄、栽插行距、分蘖肥用量和穗肥用量四因素入手进行了3年试验。初步认为,汕优63在滨海盐碱地获得高产的最佳移栽叶龄为4.9~6.0,移栽行距为29.7~34.3cm,分蘖肥用量为178.5~252kg/hm2尿素,最佳穗肥用量为90~121.5kg/hm2尿素。

利用微注射技术,把抗盐碱罗布麻DNA导入鲁棉6号。对其后代经人工配制的盐碱土筛选育成了两个耐盐碱品系91-11和91-15,在含盐量为0.51%的滨海盐碱地种植,其皮棉产量分别比受体亲本鲁棉6号增产191.7%和237.8%。对91-11和鲁棉6号在盐胁迫条件下测定其细胞质膜透性和超氧化物歧化酶(SOD)活性,结果表明,91-11在盐胁迫条件下能够维持较高的SOD活性和较稳定的膜透性,而鲁棉6号呈现相反的变化,而且差异显著。据此说明,应用这一技术能够筛选出含有抗性基因的改良品种。

By determining and correlative analyzing major soil nutrients and enzyme activities in different types of forest stands in a mixed poplar--locust experimental plantation on coastal saline--alkali site in the Yellow River Delta, following conclusions were drawn: (l) pH value of each layer of the soil profiles in mixed stands was generally lower than corresponding one in pure poplar stands, while the concentrations of organic matter and other main nutrients were higher in the mixed stands; (2)Soil microbial biomass,...

By determining and correlative analyzing major soil nutrients and enzyme activities in different types of forest stands in a mixed poplar--locust experimental plantation on coastal saline--alkali site in the Yellow River Delta, following conclusions were drawn: (l) pH value of each layer of the soil profiles in mixed stands was generally lower than corresponding one in pure poplar stands, while the concentrations of organic matter and other main nutrients were higher in the mixed stands; (2)Soil microbial biomass, urease and some other enzyme activities were commonly greater in each soil layer in mixed stands; (3) Many soil nutrients were pronouncedly correlated with enzyme activeties. These results would help reveal the mechanhisms from an aspect that why plantations of poplar mixed with black locust on poor sites usually grow better than pure poplar stands.

通过对黄河三角洲滨海盐碱地上杨树、刺槐混交试验林中各种林分类型土壤主要养分指标和几种主要酶活性的测定及相关分析得出如下结论:(1)混交林土壤各层次pH使普遍低于杨树纯林,而有机质等主要养分指标含量则高于杨树纯林;(2)混交林土壤各层次微生物碳量及脲酶等几种主要酶活性一般高于杨树纯林;(3)许多土壤养分含量和酶活性呈显著的相关关系,从侧面揭示在较差的立地上杨树、刺槐混交造林的生长效果大多优于杨树纯林的机理所在。
