我场去年开始推行洋芋芽栽技术,今年便在大面积上种植。1960年栽植24亩,单产1,558公斤;今年种植580亩,一般单产1,518.33公斤,较好的达1,740公斤/亩,比块栽产量为高。现将有关栽培技术总结于下。 一、催 芽 1.苗床的准备:选择排水良好、背风向阳地区,建土温室。室内透光,能控制温度,设有火道,作苗床以催芽。苗床宽2米,高20—25厘米,下垫半腐熟马粪10—15厘米,其上铺粗沙10厘米;平均每平方米苗床可容纳种薯65—75公斤。用阳畦和菜窖作床催芽亦可。土温室、阳畦、菜窖作床催芽优缺点的比较如表1。
My field began to implement potato budding technology last year, it is planted on a large area. 24 acres planted in 1960, yield 1,558 kilograms; 580 acres planted this year, the general yield 1,518.33 kilograms, better up to 1,740 kilograms / mu, planted than the high yield. The cultivation techniques are summarized below. First, germination 1. Seedbed preparation: choose a good drainage, leeward sunny area, built soil greenhouse. Indoor light, to control the temperature, with fire, as seedbed to germination. The seedbed is 2 meters wide and 20-25 centimeters high, with 10-15 centimeters of mat half maturity under the mat. The top layer of coarse sand is 10 centimeters. The average seedbed per square meter can hold 65-75 kilograms of seed potatoes. Yang barren and vegetable cellars can also be used for bed germination. Soil greenhouse, sunshine, cellar bed as the advantages and disadvantages of germination of the bed as shown in Table 1.
