Key points of soil Management in Pear Orchard

Pear tree has strong resistance and wide adaptability, and can be cultivated in sandy land, mountainous land and hilly land. Planting soil layer to deep, good drainage, more fertile sandy loam is appropriate.

1. Deep ploughing of pear orchard soil

Deep ploughing can deepen the root distribution layer, make the root develop to the deep soil, reduce the "floating root", improve the drought resistance and absorption ability, and have significant effects on rejuvenating the tree vigor and improving the yield and quality. Production is often used alternate deep ploughing method, all ploughing completed with 2~3 years, can be used to enlarge the hole ring groove. Deep ploughing time, to complete before autumn defoliation is good, conducive to root healing and new roots. Deep ploughing of soil should be carried out before and after defoliation, and the ploughing depth should be 10~20 cm. Ditch width 50~60 cm, depth 60~80 cm, deep ploughing combined with basal fertilizer effect is better. After ploughing, no harrowing is beneficial to soil weathering and winter snow accumulation, and ploughing in saline-alkali land can prevent salt return and prevent overwintering pests.

II. Land improvement

1. Sand and clay land improvement. Sand pressing clay and clay mixed with sand can loosen soil, thicken soil layer, improve soil and enhance water storage and fertilizer retention capacity, which is an effective measure for soil improvement in sand and clay fields. Adding organic fertilizer is also an effective measure to improve sandy land and clay land, which is beneficial to the growth and development of young trees.

2. Saline-alkali soil improvement. The physical and chemical properties of soil can be improved effectively and the harm of soil to young pear trees can be reduced by constructing platform field, introducing fresh water to wash salt, planting green manure crops, covering the ground, applying organic fertilizer and cultivating.
