Thing such as Ramulus et Folium Tamaricis, Cortex Acanthopanacis Radicis, birch-leaf pear etc., and coordinate some technology to carry out soil improvement, as number of patent application is
" greening method of a kind of strand hydraulic reclamation geavy salt alkali open ground low cost " of CN201610107176.6.Some salt-tolerant plant economy
It is worth low, thus is difficult to carry out in practice popularizing in an all-round way application, so utilizing this method improvement beach saline-alkali soil effect
The best.Currently also mention and utilize Partial controll improved method, enclose beach build up fields method as used, but the method cost is high thus producing
In be not widely used.People also mention the method for local salt discharge canal, but the method can not effectively be arranged on long terms
Salt, " a kind of Long term control method that salt-soda soil becomes good farmland " if number of patent application is CN201010601686.1 utilizes deep
Hole salt discharge alkali ditch salt discharge, bottom of trench filler, this method filler cost is big, and outlet do not built by salt discharge ditch, and saline tires out for a long time
Amass in salt discharge ditch, it is impossible to carry out effective salt discharge.
Presently suggested some crop varieties promoted in salt-soda soil, though having certain salinity and alkalinity resistance, but character is with wild
Non-hibernating eggs is similar to, and yields poorly, inferior shortcoming, thus is difficult to large scale application on producing.Common high yield and high quality
Industrial crops kind, because of not Salt And Alkali Tolerance, is widely popularized still without in salt-soda soil at present.
In a word, current Coastal beach salt affected soil improves the technology and method applied, cost height or effect
Difference, it is impossible to establishing in large scale industrial crops, thus can not extensively apply on producing, this Ye Shi China mud-flat soil salinization of soil day
The major reason that benefit is serious.Therefore, in China's developing low-cost to the beach saline-alkali ground simple and easy method effectively improved planting
Plant industrial crops generation economic benefit significant.
