摘要
通过不同生态区、施肥组合及播期对绥农 2 0高油品种产量和品质影响的试验研究 ,结果表明 :绥农 2 0在黑龙江省不同生态区产量和品质存在显著或极显著差异 ,产量在第Ⅴ生态区最高 ,脂肪含量在第Ⅵ生态区最高 ,蛋白质含量在第Ⅲ生态区最高 ,蛋脂总量也在第Ⅲ生态区最高 ;在第Ⅲ生态区不同施肥组合试验表明 ,在常量化肥做种肥的基础上 ,增施磷素活化剂、叶喷增产灵或磷酸二氢钾可显著提高产量 ,并使品质略有提高 ;适期播种 (5月初 )有利于提质增产。
The Studies on effects of different ecological regions,fertilizer Combinations and planting dates to yield and quality of Suinong 20 were conducted.The results showed there were significant differences or remark le significant differences on yield and quality of Suinong 20 in different ecological regions in Heilongjiang province.The yield of Suinong 20 was the highest in the fifth ecological region. The oil content of Suinong 20 was the highest in the fourth ecological region The protein content and total content of Suinong 20 was the highest in the third ecological region.Tests of different fertilizer combinations in the third ecological region were carried out. The results indicated that yield and quality could be increased by fertilizing phosphate or Lamina nutrition or KH 2PO 4 on the base of normal quantity chemical fertilizer as seed fertilizer. A suitable planting date at the beginning of may could also increase yield and improve quality.
