- 摘要:
- 为补充甘孜州优质耐寒牧草种类,引进高冰草在甘孜州低海拔地区进行栽培试验,分析其不同物候期(分蘖期、拔节期、孕穗期、抽穗期、结实期、枯黄期)全钾、有效磷、钙及灰分的含量。结果表明,不同物候期全钾、钙、有效磷和灰分含量存在显著差异(P<0.05),其中全钾在拔节期含量最高,有效磷和钙含量均在分蘖期最高,枯黄期有效磷和全钾含量最低,结实期钙含量最低,在拔节期和分蘖期刈割高冰草来饲养牛羊,营养价值相对较高。高冰草全钾、有效磷、钙、灰分含量与土壤含水量呈显著正相关(P<0.05),故在高冰草生长过程中需及时进行灌溉补水。
- Abstract:
- In order to supplement the species of high-quality and cold tolerant forages in Ganzi Prefecture, the cultivation experiment of Elytrigia elongata was introduced in the low altitude area of Ganzi Prefecture. And the contents of total potassium, available phosphorus, calcium and ash in different phenological stages (tillering stage, jointing stage, booting stage, heading stage, seed setting stage and withering stage) were analyzed. The results showed that there were significant differences in the contents of total potassium, calcium, available phosphorus and ash in different phenological periods (P<0.05). The content of total potassium was the highest at jointing stage, the content of available phosphorus and calcium was the highest at tillering stage, the content of available phosphorus and total potassium was the lowest at withering stage, and the content of calcium was the lowest at fruiting stage. It can be seen that cutting grass to feed cattle and sheep in the jointing stage and tillering stage had a relatively high nutritional value. The results of person correlation analysis showed that the contents of total potassium, available phosphorus, calcium and ash of Elytrigia elongata were significantly positively correlated with soil water content (P<0.05). Therefore, irrigation and water replenishment management should be carried out in time during the growth of Elytrigia elongata.
