Embodiment 1

[0023] In this example, solanaceous capsicum and leguminous bean were planted in facility greenhouses for pot planting simulation experiments. According to the traditional potting management mode, the natural light method was used to explore the effects of inoculation of indigenous fungus treatment and planting mode on soil and pepper plant-related indicators.

[0024] The operation steps are as follows:

[0025] The purple soil on the sloping land of Baoxiang River Reservoir in Kunming City was used as the test soil. After the soil was air-dried, it passed through a 2mm sieve. After mixing evenly, it was subjected to intermittent high-pressure steam sterilization for 2 hours. After drying, it was sealed to avoid contamination. The plastic film is lined before filling the soil. According to the size of the pot, each pot is filled with 4.3 kg of soil. Add Hoagland's nutrient solution to the soil as a basic fertilizer.

[0026] The bean seeds used in the pot experiment were 'Spa...

Embodiment 2

[0036] In this example, according to the measurement results of Example 1, the joint application of inoculation of native bacteria and intercropping planting mode was selected, and peppers and beans were planted in facility greenhouses for pot planting simulation experiments to explore the impact of different forms of nitrogen on soil and pepper plant-related indicators. Impact.

[0037] The operation steps are as follows:

[0038] First, according to the amount of fertilizer applied by conventional farmers, it is determined that the amount of pure nitrogen applied is 120mg·kg -1 . Secondly, adopt Solanaceae / Leguminae potted intercropping mode, plant capsicum and kidney bean, set up inoculation native bacteria treatment and intercropping planting mode, correspondingly do not apply nitrogen, apply organic nitrogen (glutamine, 120mg·kg -1 , ON120), inorganic nitrogen (ammonium bicarbonate, 120mg·kg -1 , ION120). For other conventional management, refer to Example 1. After ha...

Embodiment 3

[0044] In this example, Cucurbitaceae cucumbers and leguminous soybeans were planted in facility greenhouses for pot plant simulation experiments, and the results of Example 1 and Example 2 were supplemented and verified according to the conventional pot plant management mode.

[0045] The operation steps are as follows:

[0046] The red soil in Jinning County was used as the test soil, the soybean seeds used were 'Diandou No. 7', and the cucumbers were 'Jufengwang F1'. Refer to Example 1 and Example 2 for management methods and related index determination methods.

[0047] The basic chemical properties of the tested soil are shown in Table 3

[0048] Table 3 Basic properties of the tested soil

[0049]

[0050] After 13 weeks of the experiment, see the attached Figure 4 .

[0051] attached Figure 4 It shows that no matter what kind of planting pattern and nitrogen fertilization treatment, the inoculation of indigenous bacteria has a tendency to increase the nitrogen...

Abstract

The invention relates to an improvement method of vegetable cultivation soil under facility conditions, and belongs to the technical field of soil improvement. The method comprises the steps that an indigenous bacterium agent is applied in facility crop rhizosphere soil, and an intercropping mode of leguminous crops and vegetables is adopted to cooperate with reasonable nitrogenous fertilizer application. A preparation method of the indigenous bacterium agent comprises the following steps that rhizosphere soil of corn/soybean intercropping is collected in a field, air-dried in a shade place after collection and uniformly mixed, expanding propagation is carried out through sorghum and clover, and the indigenous bacterium agent is obtained. The invention aims at further improving an improvement method of vegetable cultivation soil under current facility conditions, providing an economical and safe method for improving vegetable soil, and scientifically and comprehensively proposing a solution, which not only can improve the problem soil under the facility conditions, but also can promote the absorption of nutrient elements such as nitrogen by vegetables, increases the utilization rate of a nitrogenous fertilizer, and reduces the application rate of the nitrogenous fertilizer.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for improving vegetable cultivation soil under facility conditions. Background technique [0002] The current use of vegetable fertilizers in my country accounts for nearly 20% of the total crops, and the amount of chemical fertilizers invested in crops under facility conditions is much higher than that in open fields. According to the average amount of fertilizer per mu of each crop, the cucumber, tomato, eggplant, and pepper grown under facility conditions ranks in the top four, while the average apparent utilization rate of nitrogen fertilizer is only about 10% [Zhu Haiyan et al., 2018]. Due to the long-term environment of high temperature, high humidity, and no precipitation leaching in facility vegetable cultivation, and the blind excessive application of nitrogen fertilizers, the problems of vegetable crop yield and quality decline, the types an...
