为探索郁金香在干旱荒漠区的表现及栽培技术,1994年我们从杭州引入栽培1年的郁金香球茎进行栽培试验。栽培地土壤为沙土,粗沙(1~0.25毫米)和细沙(0.25~0.05毫米)含量占80%以上,pH值为8.17(0~20厘米深度)。除少数品种外均能正常开花,从鳞茎大小看,均比栽植前大,但仔球数偏少,生长期未发现病虫害。栽培技术如下: 1.种植种植时间在9月下旬至10月中旬为宜。选择避风、向阳、无积水的疏松沙地,深翻、平整,做成1米宽小畦。剔除腐烂带病鳞茎,摊开后喷洒稀释100倍的40%甲醛溶液,堆聚并覆盖3~5小时,晾干。准备腐熟的堆肥,每平方米2~3公斤,加0.1~0.2公斤过磷酸钙,再加2~3公斤沙土,混匀。按15厘米行距开沟,沟深20厘米,施入5厘米厚的肥料,再覆土3
In order to explore the tulip performance in arid desert areas and cultivation techniques, we introduced the tulip bulbs cultivated for one year from Hangzhou in 1994 for cultivation experiments. The cultivated soils are sandy soils, with coarse sand (1-0.25 mm) and fine sand (0.25-0.05 mm) accounting for more than 80% and pH at 8.17 (0-20 cm depth). In addition to a few varieties can flow normally, from the size of the bulbs, are larger than before planting, but the number of small number of baby ball, no pests and diseases during the growth period. Cultivation techniques are as follows: 1 planting planting time in late September to mid-October is appropriate. Choose sheltered, sunny, loose water without sand, deep plowing, formation, made 1 meter wide 畦. Remove the diseased diseased bulbs, spread out and spray 100% diluted with 40% formaldehyde solution, and collect and cover for 3 to 5 hours to dry. Prepared composting compost, 2 to 3 kg per square meter, plus 0.1 to 0.2 kg of superphosphate, plus 2 to 3 kg of sand, mix. By 15 cm row spacing ditches, ditch 20 cm deep, applied 5 cm thick fertilizer, then soil 3
