Embodiment 1

[0019] Take heavy soda saline-alkaline soil (pH=10.58) at a depth of 0-30cm from Anguang, Da'an City, Baicheng District, Jilin Province, air-dry it, weigh 27.89kg, put it in a utensil, add 26.49 liters of water, soak for three days, add 204.60g to improve agent (weight combination ratio is humic acid 40%, zeolite 30%, acid conditioner 20%, fly ash 5%, furfural slag 5%), take out soil samples every 5 days, air-dried and sieved with No. 18 sieve (1mm Grain), detect soluble salt and CEC, carry out altogether 15 days, experimental condition and result (see table 1 and table 2) are as follows.

[0020] Experimental conditions

[0021] Apparatus: cone diameter 35.00cm, height 43.00cm, area 961.63cm 2 .

[0022] Soil weight: 27.89kg Water: 26.49L Soil bulk density 1.45g / cm 3 .

[0023] Improver: 204.60g (0.73% of soil weight).

[0024] Temperature: 8°C.

[0025] Days: 18 days before and after, 3 days for soil soaking, 15 days for experiment.

[0026] Table 1 Changes of soluble...

Embodiment 2

[0032] In Anguang, Daan City, Baicheng District, Jilin Province, severe saline-alkali land (pH=10.35), the designated area is 11000m 2 , of which 10000m 2 Do modifier experiment, 1000m 2 as a control area.

[0033] In spring, use a tractor to plow the ground, pour water into the field for three days, add 8.5 tons of improvers (weight ratio: 40% humic acid, 30% zeolite, 20% acid conditioner, 5% fly ash, 5% furfural slag); add Organic fertilizer (weight combination ratio: 45% of fully fermented chicken manure, 50% of crushed straw, 5% of wood vinegar) 8.5 tons, properly mixed, and after 10 days, use a tractor to rake the field to level off, and transplant rice seedlings. After two months or so, the rice seedlings in the experimental area were growing brightly green, while 60-70% of the rice seedlings in the control area were all dead, which became an obvious contrast. The rice in the experimental area was not abnormal and ripened on time, and 7000kg of rice was harvested afte...

Abstract

The invention discloses a soda saline-alkali land comprehensive treatment agent and a use method thereof, and belongs to the technical field of control agents for improving moderate and severe soda salinization. The comprehensive treatment agent consists of a modifier and an organic fertilizer, wherein, components of the modifier comprise humic acid, zeolite, a acid conditioner, fly ash and furfural residue; and the components of the organic fertilizer comprise fermented chicken manure, crushed straw and wood vinegar liquid. The comprehensive treatment agent is applied at 13-17t per 1 hectare of saline-alkali land before harrowing and transplanting. The action mechanism of the soda saline alkali land comprehensive treatment agent integrate physical and chemical functions of chemical salifying, complexing, neutralizing, ion exchange, adsorption, desorption, passivation, fixing, preventing salt accumulation, emulsion breaking and like; which increase CEC by times, desorbs and leaches base and basic group in soil, significantly decrease the pH value, greatly reduce soluble Na ions; and a formed anti-salt accumulation plow pan structure really takes effect of 'salt isolation' and 'alkali decrease', thus realizing rice harvest in the same year of construction and cultivation.

Description

technical field [0001] The invention belongs to the technical field of improving medium and severe soda saline-alkali soil chemical control agent. technical background [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Soil salinization refers to the soil-forming process in which saline-alkali components accumulate in the soil under the influence of natural or human factors, making other types of soil gradually evolve into saline soil. The mechanism is that during the weathering process of the ore, the easily leached and extremely leached salts become the main compounds accumulated in the soil, namely NaCl, NaCl 2 SO 4 , NaHCO 3 , MgCO 3 , MgSO 4 , MgCO 3 , CaSO 4 , CaCO 3 Wait. [0003] The harmful effect of saline soil generally refers to that due to the excessive soluble salt in the soil, it is difficult for seeds and crop roots to absorb water, which seriously affects the normal growth of germination and crops. Moreover, the vast m...
