金华、绍兴两个薄壳山核桃种在红河地区的表现

通过对金华、绍兴2个薄壳山核桃种10多年引种调查认为：薄壳山核桃2年生苗移栽后,4~7 a进入结实期,10 a后进入大量结实期,其中：金华13年生最高株产16 kg;果形大,种实单粒重6.5~9.4 g,种壳厚0.9~1.1 mm,出仁率51%~56.9%,粗脂肪76.9%~78.5%,蛋白质8.5%~9.7%,可作为主栽品种发展。绍兴13年生最高株产14.6 kg,平均7 kg;单果较小,核果重5.5~6.3 g,核壳厚1.1~1.2 mm,出仁率52%~53.8%,种仁饱满,粗脂肪74.1%~74.4%,蛋白质7.5%~8.3%,可为供种或授粉树适当发展。上述2个品种适宜红河州海拔800~1 600 m的地方推广栽培。

Performances of Two Species of Carya illinoensis as" Jinhua" ,"Shaoxing" in the Red River Area, Yunnan Province

Two species of Carya illinoensis as ＂Jinhua＂,＂Shaoxing＂ were introduced and investigated more than 10 years.The results showed that 2 years old C.illinoensis seedlings after transplanted,the grain filling stage in 4~7 a,large firm period was after 10 a,of which： 13 years old ＂Jinhua＂ has the highest strains production at 16 kg,with big fruit,single-seed weight of 6.5~9.4 g,shell thickness of 0.9~1.1 mm,kernel rate of 51%~56.9%,crude fat of 76.9%~78.5%,protein of 8.5% ~ 9.7%,which can be developed as main-cultivation species.13 years old ＂Shaoxing＂ has the highest strains production at 14.6 kg,an average of 7 kg,with smaller fruit,single-seed weight of 5.5~6.3 g,shell thickness of 1.1~1.2 mm,kernel rate of 52%~53.8%,kernel plump,crude fat of 74.1% ~ 74.4%,protein of 7.5% ~ 8.3%,which can be developed as seed-production or pollination trees.The two varieties were suitable for promotion and cultivation in the altitude of 800~1 600 m in Red River State area.
