绿肥是温州专区早稻的主要基肥。沿海平原地区以栽培黄花苜蓿为主,山区半山区则以紫云英为多。全区1959年冬种面积261万亩,其中黄花苜蓿约占70—80%。黄花苜蓿炭疽病往年仅在个别地区发生,受害轻微,未引起注意。1959—60年各地均普遍发生,而且发病时间早,传播很快,对产量造成一定的损失。为了摸清发病规律,总结群众防治经验,保证绿肥产量的不断提高,我们特对此进行了初步调查。
Green manure is the main base of Wenzhou early rice. Coastal plains are mainly cultivated with alfalfa, while mid-mountainous areas are dominated by asparagus. The area of 1959 winter 26610000 acres of area, of which accounted for about 70-80% of alfalfa. Medicago falcata has only occurred in some areas in previous years, with minor injuries and no attention. 1959-60 years are common in all parts of the country, and the onset time is early, spread quickly, resulting in some loss of production. In order to find out the law of onset, summarize the experience of the masses to prevent and control to ensure the continuous improvement of green manure production, we conducted a preliminary investigation of this.
