1. Soaking in water for treating salinization
The results of 6 water soaking treatments are shown (see table 1), and the soil soluble salt and SO treated by different treatments 4 2- The total content of nitrogen, phosphorus and potassium is reducedAnd low, the water soaking can reduce the salt content of the soil and the nutrient content of the soil, and the nutrient reduction rate of the water soaking in the plowing process is higher than that of the no-tillage water soaking. Wherein the total nitrogen reduction rate of the soil treated in no-tillage for 5 days is obviously lower than that of the soil treated in no-tillage for 10 days and in tillage for 15 days, the total phosphorus and total potassium reduction rates are respectively obviously lower than those of the other 5 treatments, the total nutrient (total nitrogen, total phosphorus and total potassium) reduction rate of the soil is 38.68 percent, the total nutrient and total potassium are the lowest among the 6 treatments, and the total nutrient and total nitrogen and total potassium reduction rate shows that the soluble salt content reduction rate of the soil treated in no-tillage for 5 days is obviously lower than that of the soil treated in tillage for 10 days and in tillage for 15 days, but the difference with the other 3 treatments is not obvious, and the SO content of the soil is different from that of the soil treated in no-tillage for 10 days and in tillage for 15 days 4 2- The content is reduced along with the prolonging of the soaking time, but the reduction range is small, and the results show that the no-tillage soaking water has good effect in 5 days, and the reduction content of nutrients is minimum, so that the optimal salt washing treatment is recommended.
TABLE 1 variation of nutrient content of soil treated with different soaking water
2. Application of wormcast for relieving salinization
And (3) experimental design: the tested crop is the zanthoxylum piperitum, the growth vigor of seedlings is good and consistent, the height of the seedlings is about 20cm, and 4 to 5 true leaves are provided. The pot culture container is a plastic pot with the diameter of 35cm and the height of 30 cm. The potting soil is greenhouse salinized soil (the basic nutrients are shown in table 2), and about 7.5kg of soil contained in each pot is fully mixed with fertilizer, and pepper seedlings are transplanted after one week of precipitation. The fertilizer is compound fertilizer and wormcast. The compound fertilizer is Shimapai containing N, P 2 O 5 、K 2 O accounts for 15.0%, 15.0% and 15.0% respectively; the soil to be tested is greenhouse soil, and the wormcast is a product of the subject matter group for converting agricultural wastes by using earthworms, and the nutrients of the wormcast are shown in the following tables (table 2 and table 3).
TABLE 2 basic physicochemical Properties of soil
TABLE 3 nutrient content of wormcast
The test set 7 treatment groups (see table 4) without any fertilization before treatment, and the fertilizer required by the potted plant is converted based on the fertilizer required by the material required for investigating the growth period of the pepper in the whole growth period. The treatment technology of salinization of facility soil is explored through the desalinization rate of the soil before and after wormcast application, basic nutrients of the soil, morphological growth characters of crops and root growth characters.
CK is not fertilized, T1 is earthworm fertilizer, T2 is pure fertilizer, and T3.75% of fertilizer is arranged; t4.75% of chemical fertilizer +/-600 kg/mu of wormcast; t5.75% of chemical fertilizer +/-1200 kg/mu of wormcast; t6.75% of chemical fertilizer +/-1800 kg/mu of wormcast, 7 treatments, wherein the soil mass of each pot is 7.5kg, and each treatment is repeated for 5 times, and the number of the pots is 35. 4 gradient wormcast are applied to the test soil (the application amount is 0 and 600kg/667m respectively) 2 、1200kg/667m 2 、1800kg/667m 2 Indicated by T3, T4, T5 and T6), the amount of wormcast applied and the content of soluble salts in soil after application are shown in Table 4.
TABLE 4 fertilizing amount and soluble salt content for different treatments
2.1 test results
From the figure 1, the decrease rate of the soluble salt in the soil after the wormcast with different concentrations is obviously changed, the decrease rate is represented as that T1 is the highest, T5 is the second, the difference between the decrease rate and the control is obvious, and T2, T3, T4 and T6 are all lower than the control, so that the application modes of the wormcast and the compound fertilizer with different application amounts can be determined to have obvious influence on the decrease of the soluble salt content in the facility soil.
As can be seen from Table 5, the application of wormcast with different concentrations has an influence on the plant height of crops, the stem thickness, the dry weight of the overground part and the dry weight of the underground part, and the difference of the dry weights of the overground part and the underground part of T6 is not significant.
TABLE 5 Effect of different treatments on morphological growth traits
As can be seen from Table 6, the application of different concentrations of wormcast has significant effects on the root length, average diameter, surface area, volume and branch number of crops. The root length, the surface area and the volume of the T1 and the T5 are all the highest, and the others are obviously higher than the control except the root length; it was therefore determined that the T6 treatment promoted the growth of the root system of the crop.
TABLE 6 Effect of different treatments on growth characteristics of crop roots
TABLE 7 Effect of different treatments on soil nutrient content
The results show that: the application of 1800 kg/mu of pure wormcast can lead the reduction rate of soluble salt content of facility soil to reach 46.69 percent; the salt rejection rate is 39.97% by applying 75% of compound fertilizer and 1200 kg/mu of wormcast, but comprehensive performance of morphological characters, root system characters and soil nutrient content of the peppers is provided, and the salinization is relieved by applying 75% of compound fertilizer and 1200 kg/mu of wormcast to facility soil with soluble salt content of 5-8 g/kg.
