宁南山区豌豆高产栽培的农业气象措施研究

Study on Agrometeorological Measures about the High-Production Techniques of Peas in the Southern Mountain Area Part of Ningxia

[目的]分析宁南山区豌豆需水规律，土壤水分供应状况，确定豌豆适宜播种期，高产、稳产的农业气象指标及利用水分的有效方法等。[方法]以西吉县为例，应用裂区设计，进行分期播种试验，探讨不同深度播种、木盆栽种、灌水处理等方法对豌豆生产的影响。[结果]当地豌豆的播种期在3月下旬-4月下旬；干旱年份，适宜播种深度在13 cm左右，降水偏多年份，播种深度在8～13 cm；豌豆出苗时要求土壤水分百分率＞12%；豌豆收割后，可以地膜复种大白菜；豌豆根腐病与干旱基本是同时发生。[结论]研究结果为干旱山区充分利用气候资源，夺取高产提供了参考。

The soil water requirement,soil water condition of pea in the southern mountain area part of Ningxia were analyzed, to determine optimum sowing date of pea,agrometeorological indexes for high and stable yield,and take effective measures of soil moisture etc. [Method] Taking Xiji County as an example, using split plot design,the planting-date experiments were conducted, for studing the effects of different sowing deeps,irrigation treatments, wood potted on production of peas. [Result] The sowing time of peas was late March to late April. The optimum sowing deep of peas was about at 13 cm in drought years, on the contrary was in 8-13 cm. The minimum soil moisture of pea emergence was about≥12%. The chinese cabbage coulde be cultivated under film after peas harvesting. The rot of pea and drought were likely to occur simultaneously. [Conclusion] The results provided references for high and stable yield of pea that make full use of climate resource in dry areas.
