为了提高大蒜产量,增加经济效益,我县从1985年开始,进行大蒜由春播改秋播和由本地品种改引山东优种的“两改”试验。实践证明,大蒜由春播改秋播,由于经过长期低温,提高了抽苔率,同时在高温季节来临前,有充足的时间生长,增加了营养物质积累,蒜台长的粗、蒜头大;本地种改优种,由山东引入蒲棵蒜,比当地品种生长势强、产量高。1988年秋季,全县示范推广大蒜两改栽培320亩,一般亩产蒜苔250—300公斤,蒜头600—800公斤,每亩纯收入1000多元,高产地块,亩产蒜苔500公斤,蒜头1000公斤。春播本地品种成熟期晚10天左右,亩产蒜苔仅40—50公斤,蒜头400—500公斤。几年来观察,秋播大蒜的生长发育和管理季节是:秋分播种,小雪冬灌,大雪盖草,惊蛰返青,
In order to increase the output of garlic and increase economic benefits, our county started from 1985 to carry out the “two changes” experiment in which garlic was sowed by spring sowing and autumn sowing by local varieties to Shandong superior breeds. Practice has proved that garlic sowing by the autumn sowing, due to long-term low temperature, increased moss rate, while the high temperature season before the advent of sufficient time to grow and increase the accumulation of nutrients, garlic Taiwan long coarse, garlic large; local Seed improved varieties, introduced by Shandong Po Po garlic than the local varieties growing strong, high yield. The fall of 1988, the county model to promote the reform of two cultivated garlic 320 acres, the general mu produce garlic 250-300 kilograms, 600-800 kilograms of garlic, per mu net income of more than 1,000 yuan, high yield plots, per mu yield of 500 kg garlic, garlic 1000 kg . Spring sowing local varieties mature about 10 days late, mu produce only 40-50 kilograms of garlic, garlic 400-500 kg. Observed in recent years, autumn sowing garlic growth and management of the season are: autumn seeding, snow and winter irrigation, snow cover grass, Jingzhe green,
