Embodiment 1

[0035] The preparation of embodiment 1 soilless cultivation substrate

[0036] Fermentation treatment of corncobs: add 0.003kg of bacterial agent per kilogram of corncobs before fermentation. The bacterial agent is purchased from Beijing Jingpuyuan Biological Engineering Co., Ltd., the trade name is organic waste starter, and 0.003kg of gypsum powder is added at the same time, and the C :N ratio to 25:1, the moisture content of the material during fermentation is controlled at 60% (water can be added appropriately), stacked for fermentation, turned over once a week, and the fermentation material is sampled at different fermentation periods, and the fermentation of the sample is terminated. And the sample was dried, and the physical and chemical indicators (Table 1) of the obtained corn cob fermentation substrate were detected for subsequent use.

[0037] Table 1 The physicochemical properties of the obtained corn cob fermentation substrate obtained by different fermentation da...

Embodiment 2

[0043] The application of the substrate of embodiment 2 different stacking time in cucumber cultivation

[0044] The substrate of the formula in Example 1 is used for the cultivation of cucumbers under greenhouse conditions. The greenhouse has fully automatic temperature control and ventilation facilities, which can ensure that a relatively stable and suitable growth environment is provided for the test materials during the test. The results are shown in Table 2.

[0045] The specific method of cucumber soilless cultivation is as follows: When the two leaves of the cucumber are in one center, they are planted in the cultivation medium, and drip irrigation is used, and the irrigation is performed twice a day for 20 minutes each time.

[0048] Note: Each lowercase letter represents the difference level of p<0.05.

[0049] It can be seen from Table 2 tha...

Embodiment 3

[0050] The influence of the substrate of embodiment 3 different stacking time on the photosynthetic rate of cucumber

[0051] The matrix of the formula in Example 1 is used for the cultivation of cucumbers under greenhouse conditions. The greenhouse has fully automatic temperature control and ventilation facilities, which can ensure that a relatively stable and suitable growth environment is provided for the test materials during the test.

[0052] The photosynthetic rate of cucumber plant leaves was measured by using a photosynthetic instrument Li6400 during the cucumber growth period, and the results are as follows: figure 1 shown by figure 1It can be seen that the net photosynthetic rate of cucumbers grown on the substrate stacked for 35 days was significantly higher than that of the substrates stacked for 45 days and 65 days.

Abstract

The invention discloses a corn cob fermentation substrate and its preparation method and application. By controlling the physical and chemical properties such as water holding porosity, air porosity and bulk density in the corn cob fermentation process, the fermentation end point is determined, and a cultivation substrate with excellent performance is obtained. . The cultivation substrate has short fermentation time and good physical and chemical properties. The substrate prepared by this method can increase the temperature of the root system of the plant during planting in winter and promote the growth of the plant; at the same time, the invention realizes the resource utilization of corncobs, and has obvious social and economic benefits. benefits and environmental ecological benefits.

Description

technical field [0001] The invention relates to a soilless cultivation technology, in particular to a corn cob fermentation substrate and a preparation method and application thereof. Background technique [0002] As a large agricultural country, my country has a large area of ​​agricultural product cultivation, and a large amount of agricultural waste, such as rice, wheat, corncobs, sawdust and other crops, will be produced in the process of agricultural production, which has brought considerable work pressure to the relevant processing departments. Therefore How to effectively deal with agricultural waste has become an urgent problem for us to solve. [0003] At present, my country's treatment of agricultural waste is relatively simple and rough, usually by centralized incineration or on-site backfilling. Centralized incineration or on-site backfilling not only wastes manpower, material and financial resources, but also causes great pollution to the environment. [0004] ...
