Embodiment 1

[0049] Set up facility sheds on the soil cultivated land, and set drainage ditches with a width of 20-30cm and a depth of 80-100cm around the facility shed. A water supply device is installed in the facility greenhouse, and the water supply device is selected from one or a combination of droppers or sprinkler irrigation equipment.

[0050] In the gap between crops in the facility greenhouse, earthworm feed is plowed into the soil plow layer. After plowing, ridges and furrows should be formed. The width of the ridges is 20-50 cm, and the distance between the ridges is 5-20 cm. The input amount of the selected earthworm feed includes 0.5-1.5 tons / mu of straw and 1.0-4.0 tons / mu of organic fertilizer. The straw needs to be crushed and then pre-composted for 7-15 days. The straw is selected from one or more of rice straw, vegetable waste, mushroom residue, green manure or grass. The organic fertilizer is selected from one or more mixtures of decomposed livestock and poultry manur...

Embodiment 2

[0054] In a 5-year watermelon continuous cropping greenhouse in a test base in Shanghai, watermelon continuous cropping obstacles are relatively serious (about 40% of watermelon wilts occurred in the previous crop) and the soil type is fluvo-aquic soil. Basic physical and chemical properties of barrier soil: Basic soil properties: pH7.72, electrical conductivity 1.18mS / cm, organic matter content 18.1g / kg, total nitrogen content 1.46g / kg, total phosphorus content 2.04g / kg, total potassium content 12.83g / kg kg.

[0055] Drainage ditches with a width of 24 to 26 cm and a depth of 85 to 95 cm are set around the facility greenhouse. A water supply device is installed in the facility greenhouse, and the water supply device is a dropper and sprinkler irrigation equipment. Different test areas in the facility greenhouse are separated by a 1m deep geomembrane to prevent mutual interference and influence.

[0056] After the watermelons are harvested in autumn in the watermelon continu...

Embodiment 3

[0060] In the above-mentioned Example 2, the soil in the facility greenhouse where the worms were put in and the earthworms were put in and the earthworms were not put in were tested, and the data on the physical and chemical properties of the soil are shown in Table 1.

[0061] It can be seen from Table 1 that the soil pH, electrical conductivity, and bulk density of the continuous cropping barrier soil in greenhouses in facilities that were fed with William's Ringworm and Chizi Eisensis (Taiping No. 2) were improved to varying degrees. Available potassium and organic matter are 30.6-36.7%, 31.3-45.6%, 18.8-19.3%, 34.7-37.2%, 53.3-64.4% higher than conventional treatment, respectively, and the ecological benefits are remarkable.

Abstract

The invention provides a method for improving facility continuous-cropping soil by means of earthworms. Between rotations of crops in a facility greenhouse, a soil plough layer is turned over so thatearthworm feed can be applied into the soil plough layer, then young earthworms are put into soil, then the soil is covered with wet straw, and then the next crop is planted. According to the providedmethod for improving the facility continuous-cropping soil by means of the earthworms, the current development requirements of the ecological agriculture and the economic society are combined, a proper living environment is created according to the living characteristics of the earthworms, soil improvement, agricultural waste resource utilization and earthworm breeding are combined, the conversion efficiency of agricultural waste nutrients is improved, the ecological environment quality of the farmland soil is improved, the agricultural green production concept is deepened, and the yields andthe quality of agricultural products are improved. The provided method for improving the facility continuous-cropping soil by means of the earthworms has the advantages that the conception is novel,economic and ecological benefits are high, management is simple and convenient, technical operation is easy to master, and the like, and is worthy of application and popularization.

Description

technical field [0001] The invention belongs to the technical field of soil improvement and plant protection, and relates to a method for using earthworms to improve facility continuous cropping soil, in particular to a method for using earthworms instead of traditional physical and chemical methods to improve continuous cropping obstacle soil in facility agriculture. Background technique [0002] With the reduction of arable land area, the facilities, intensification and specialization of agricultural development, facility agriculture develops rapidly, and facility greenhouse is the main form of facility agriculture, which has a high degree of industrialization and good benefits, but its multiple cropping index is high and the input of chemical fertilizers and pesticides is high. Large amount of fertilizer, low fertilizer utilization rate, and common continuous cropping phenomenon. Even under normal cultivation and management conditions, facility greenhouses are prone to soi...
