| Abstract: | The experiment on green manure manuring is carried out in the arid valleys of the upper reaches of Minjiang River in rainy season of the successive 4 years so as to fertilizing soil, increasing moisture utilization and promoting the growth of the young growths of Prunus armeniaca. The results are as follows: (1) The moisture content in soil of 0-40 cm in depth is increased by 0 39 g/kg in dry season by planting Onobrychis viviaefolia, and the unit weight of soil of 0-20 cm in depth is reduced by 0 01 g/cm3; the moisture content in soil of 0-40 cm in depth is increased by 0. 55 g/kg in dry season by planting Melilotus officonahs, and the unit weight of soil of 0-20 cm in depth is reduced by 0.04 g/cm3; the moisture content in soil of 0-40 cm in depth is increased by 0. 30 g/kg in dry season by planting Astragalus adsurgens, and the unit weight of soil of 0 20 cm in depth is reduced by 0. 03 g/cm3; (2) By green manure manuring, the organic matter content in soil is increased by 0. 10-0.46 g/kg, the CaCO3 content in soil is reduced by 0.93-104 g/kg, and the contents of available nitrogen, available phosphorus and CEC are increased by 5.9 - 19 3 mg/kg, 1 26-2.46 mg/kg and 0.68 - 1.00 mg/kg; (3) It promotes significantly the growth of the height and surface-diameter of the young growths of Prunus armeniaca to plant Onobrychis viciaefoiia and Melilotus officonahs, especially to plant Onobrychis viciaefolia. |
| Keywords: | upper reaches of the Minjiang River arid valley young growth of Primus armeniaca green manure |
