Abstract
The present invention is one kind of molded plant bag for improving alkaline land and belongs to the field of alkaline land improving technology. Inside the molded plant bag of 55-65 cm length, 35-45 cm width and 3-10 cm height, is one auxiliary bag holding chemical soil improving agent. Inside the molded plant bag, there are corn stalk powder 25-35 wt%, rice strawpowder 17-23 wt%, sandy soil 17-23 wt%, barnyard manure 8-12 wt%, soil water and fertilizer maintaining synergist 3-7 wt%, salt and alkali tolerant plant seed 3-5 wt% and chemical soil improving agent 8-12 wt%. The present invention can change the physical and chemical properties completely, increase organic matter in soil, loosen soil and promote growth of plant.
Description
technical field [0001] The invention belongs to the field of improving saline-alkali soil. Background technique [0002] Saline-alkali land is a soil type widely distributed on the earth, and the global saline-alkali land area is 95438×10 4 hm 2 , accounting for about 25% of the total land area, distributed in arid regions on all continents of the world, mainly concentrated in Eurasia, Africa and western North America. There are about 3300×10 saline-alkali land in my country 4 hm 2 , accounting for about 4% of the global saline-alkali land area, mainly distributed in the northeast, northwestern inland areas of North China and coastal areas north of the Yangtze River. The improvement of saline-alkali land is a worldwide problem, and at the same time, saline-alkali land has become the biggest obstacle to the construction of ecological environment and the sustainable development of agriculture in my country. At present, the measures to control saline-alkali land mainly inc...
