四倍体刺槐生态饲料林栽培试验

四倍体刺槐是近几年培育成功的刺槐新品种,它不但保持了普通刺槐的原有属性,同时又具有很多新的特性.通过对四倍体刺槐生态饲料林栽培技术的试验研究,结果表明,不同定植密度对苗木成活率无显著影响,但对采割量影响显著.以每667 m2定植3 300株枝条采割量最大;四倍体刺槐2号和5号与普通刺槐相比,粗纤维和粗蛋白含量高,灰分含...     

大字杜鹃播种育苗技术研究

以大字杜鹃为材料,对播种育苗技术进行研究,结果表明,种子发芽适宜的光照强度为1 000～2 000 Lx;种子最佳催芽处理方法是:种子采集调制后冷藏,播种前浸泡48 h;最适宜的播种基质为腐殖土+土沙混合,比例为2:1 ,再覆盖1 cm厚粉碎的苔藓.播种育苗适宜在温室与塑料大棚中进行,出苗率分别达到85% 和61%,当...

中国亚热带稻田土壤碳氮含量及矿化动态

Dynamics of soil organic matter in a cultivation chronosequence of paddy fields were studied in subtropical China. Mineralization of soil organic matter was determined by measuring CO2 evolution from soil during 20 days of laboratory incubation. In the first 30 years of cultivation, soil organic C and N contents increased rapidly. After 30 years, 0-10 cm soil contained 19.6 g kg^-1 organic C and 1.62 g kg^-1 total N, with the corresponding values of 18.1 g kg^-1 and 1.50 g kg^-1 for 10-20 cm, and then remained stable even after 80 years of rice cultivation. During 20 days incubation the mineralization rates of organic C and N in surface soil （0-10 cm） ranged from 2.2% to 3.3% and from 2.8% to 6.7%, respectively, of organic C and total N contents. Biologically active C size generally increased with increasing soil organic C and N contents. Soil dissolved organic C decreased after cultivation of wasteland to 10 years paddy field and then increased. Soil microbial biomass C increased with number of years under cultivation, while soil microbial biomass N increased during the first 30 years of cultivation and then stabilized. After 30 years of cultivation surface soil （0-10 cm） contained 332.8 mg kg^-1 of microbial biomass C and 23.85 mg kg^-1 of microbial biomass N, which were 111% and 47% higher than those in soil cultivated for 3 years. It was suggested that surface soil with 30 years of rice cultivation in subtropical China would have attained a steady state of organic C content, being about 19 g kg^-1.
