鸭、雪花梨是我省中南地区的主栽水果品种,具有生育期长,耗水量大的特点。这在当前工农业用水急剧增加,水资源日趋紧张的今天,是应慎重考虑解决的问题,所以在梨园中采用麦秸覆盖方法是有现实意义的。我们在晋县河头村沙地梨园进行了两年早期灌水,结合麦秸覆盖,后期适当控水的试验。覆盖方法:梨园春季追肥灌水后,用10厘米左右厚的麦秸覆盖树盘,上压一层2—3厘米的薄土,以防麦秸被风吹飘失,树盘面积以树冠外沿为标准打埂。每次灌水量,以水层厚15厘米左右为宜。干旱季节可适当增浇1—2次。树盘内灌适量水(于4月上旬,6月上旬各一次),树盘内灌适量水加麦秸覆盖(日期同上,灌第一次水后覆盖麦秸),树盘内灌多量水(日期同上,浇水多1/3—1/2),三种灌水方式。从灌水后每隔10—15天定期测定10—40厘米,
Duck, Snow pear is the main varieties of fruits in central and southern regions of our province, with a long growth period, water consumption characteristics. This is the current industrial and agricultural water consumption increased sharply, water resources are increasingly tense today, should be considered carefully to solve the problem, so the pear in the straw coverage method is of practical significance. We carried out two years of early irrigation in the sandy orchard in the village of Hsitou, Jinxian County, combined with wheat straw cover and later water control experiments. Cover method: Pear spring top dressing after irrigation, with about 10 cm thick straw cover tree, pressure on a layer of 2-3 cm of thin soil to prevent wheat straw was the wind drift, the tree plate area to the crown as the standard Fight. Each irrigation volume, the water layer thickness of about 15 cm is appropriate. Drought season may be appropriate to pour 1-2 times. The amount of water in the tree tray (in early April, once in early June), the amount of water in the tree tray with straw and straw cover (date as above, filling the first water after the straw cover) Ibid, watering more 1 / 3-1 / 2), three kinds of irrigation methods. After the irrigation from 10-15 cm regularly measured every 10-15 cm,
