摘要
以三角叶滨藜为材料,研究了播种密度及氮肥对三角叶滨藜生长、鲜叶产量及品质的影响。结果表明:①3.75(B1)、7.5(B2)kg.hm-2的播种量,100(N2)、200(N3)kg.hm-2的施氮量均可以显著提高三角叶滨藜的株高及鲜菜产量。7.5(B2)kg.hm-2的播种量,200(N3)kg.hm-2施氮量较有利于三角叶滨藜鲜菜总产量的增加。②100(N2)-200(N3)kg.hm-2范围内的氮肥能显著提高三角叶滨藜Vc及蛋白含量。15(B4)kg.hm-2的播种量不利于三角叶滨藜品质的积累,Vc及蛋白含量显著下降。
A field experiment was carried out to study the effects of seeding rate(3.75,7.5,11.25, 15 kg·hm-2) and N application(0,75,150,225 kg·hm-2) on the growth,fresh weight and quality of Atriplex triangularis.in the coastal area of north Jiangsu province.The results showed that:(i) Appropriate amount of seeding rate(3.75,7.5kg·hm-2) and N(100,200kg·hm-2) could promote the growth and increase the total fresh weight.The best combination was B2N3,and the seeding rate was 7.5kg·hm-2,N was 200 kg·hm-2;(ii) Appropriate amount of N(100,200 kg·hm-2) could promote the content of Vc and protein.The seeding rate 15 kg·hm-2 was useless for the accumulation of quality.
