Problems solved by technology

Nematodes are mainly distributed in the soil layer of 0-20cm in the soil. 15-30°C is the suitable temperature for growth and reproduction of nematodes. If the temperature is lower than 10°C, they will be dormant in the form of cysts. When the temperature reaches above 10°C, the eggs can hatch. For larvae, high temperatures above 40°C and low temperatures below 5°C can inhibit the survival of larvae and the hatching of cysts. Some studies have found

Example Embodiment

[0025] In Embodiment 1, the method includes the following steps:

[0026] A, such as figure 1 As shown, water spinach is sown in rows in greenhouse 0; the plants 14 in the embodiment of the present invention are water spinach, which belongs to the dwarf type of leafy vegetables, which facilitates the entry of the ditching and spreading device in the later stage, compared with grapes and passion fruit The growth cycle is short, the cost is low, and there is no need to remove the vine frame. On the other hand, the water spinach is resistant to heat and is suitable for summer growth.

[0027] B. Detect the soil at the roots of water spinach. When cysts are formed on the roots of water spinach, it indicates that nematodes gather in the roots of water spinach, which indicates that it is suitable for squash operation. According to the adjustment of the cycle from sowing to cyst formation, control the sump time in mid-July , Water the soil in the greenhouse 0, keep the soil moisture at 80...

Example Embodiment

[0041] Example 2 is basically the same as Example 1, except that it is a method for inhibiting soil nematodes in greenhouses. The method includes the following steps:

[0042] A. Sow water spinach in rows in greenhouse 0;

[0043] B. According to the adjustment of the period from sowing to the formation of cysts, control the dull shed time at the end of July. Water the soil in the greenhouse 0, keep the soil moisture at 80-85%, and close the greenhouse 0 for the boring shed. The temperature can reach 60-80℃, and the stuffy shed time is 7 days;

[0044] C. Open the greenhouse 0 for heat release, and the heat release time is 2h;

[0045] D. Ditch the soil surface in the greenhouse 0, apply cooling material and cover the soil to make the soil temperature drop instantaneously. The ditch depth is 18cm. The cooling material is dry ice and liquid nitrogen. The usage of dry ice is 150kg / mu. The amount of liquid nitrogen used is 100kg / mu.

[0046] E. Cover the soil in the greenhouse with a fil...

Example Embodiment

[0048] Example 3 is basically the same as Example 1, except that it is a method for inhibiting soil nematodes in greenhouses. The method includes the following steps:

[0049] A. Sow water spinach in rows in greenhouse 0;

[0050] B. According to the adjustment of the period from sowing to cyst formation, control the dull shed time in mid-August, water the soil in the greenhouse 0, keep the soil moisture at 80-85%, and close the shed 0 for the dull shed, in the greenhouse 0 The temperature can reach 60-80℃ for 8 days;

[0051] C. Open the greenhouse 0 for heat release, the heat release time is 3h;

[0052] D. Ditch the soil surface in the greenhouse 0, spray cooling material and cover the soil to make the soil temperature drop instantaneously, the trench depth is 20cm, the cooling material is dry ice and liquid nitrogen, and the usage amount of dry ice is 130kg / mu. The amount of liquid nitrogen used is 110kg / mu.

[0053] The test data shows that after every 1000-1500 nematodes undergo...

Abstract

The invention relates to a gathering and elimination implementation method for greenhouse soil nematodes, which belongs to the technical field of the prevention and control of soil nematodes. The method comprises the following steps: (A) plants are planted by columns in a greenhouse; (B) soil is watered in the greenhouse, the greenhouse is tightly closed to carry out sealing, and the duration of sealing is seven to ten days; (C) the greenhouse is opened to release heat; (D) the soil surface in the greenhouse is ditched, a cooling material is applied and earthing is carried out, so that the temperature of the soil is instantly decreased, and the ditching depth is 15 cm to 20 cm. According to the invention, nematodes are gathered at the roots of the plants, the nematodes in greenhouse soil either adults, larvae or cysts can all be effectively killed by adopting a cold-heat combination method, female nematodes which survive by luck cannot completely develop in a high-temperature environment, reproductive capacity is impaired, and the probability of soil nematode recurrence is decreased. Moreover, the method reduces the usage of medicament, reduces the damage to the soil, and is safe,reliable and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling soil nematodes in greenhouses, and relates to a method for preventing and controlling soil nematodes in greenhouses, in particular to a method for gathering and eliminating soil nematodes in greenhouses. ( Background technique [0002] The soil nematode is a highly specialized omnivorous phytopathogenic nematode that uses aerobic respiration. The nematodes mainly harm the roots of various vegetables, which are characterized by the formation of spherical or conical white nodules of different sizes on the fibrous roots of young roots, and some are bead-shaped. The above-ground parts of the damaged plants grow short and slow, with abnormal leaf color, few fruits, low yield, and even cause early death of the plants. Nematodes have become a kind of "cancer" in greenhouse vegetable cultivation. Nematodes are mainly distributed in the soil layer of 0-20cm in the soil. 15-30°C is the ...
