Embodiment 1

[0020] The organic fertilizer provided by the invention is used to reduce the incidence of cucumber root-knot nematode, and its raw materials are as follows:

[0021] 35 kg of vermicompost, 25 kg of crushed corn stalks, 29 kg of sawdust, and 10 kg of vermiculite. The crushed corn stalks are 3-4 cm long.

[0022] Provided by the invention is used to reduce the organic fertilizer preparation method of cucumber root-knot nematode incidence rate, carry out as follows:

[0023] A. Weigh vermicompost, crushed corn stalks, sawdust and vermiculite respectively according to the above weight ratio.

[0024] B. Fully mix the crushed corn stalks, sawdust and vermiculite, and wet it with an appropriate amount of water, so that the water content of the compost material is 50-60%. Pile up crushed corn stalks, sawdust, vermiculite, etc. in a plastic shed or in the open air (to shelter from the rain), and add Puyuan brand organic fertilizer starter. Fermentation is carried out under the tem...

Embodiment 2

[0027] The organic fertilizer provided by the invention is used to reduce the incidence of cucumber root-knot nematode, and its raw materials are as follows:

[0028] 38 kg of vermicompost, 29 kg of crushed corn stalks, 28 kg of sawdust, and 9 kg of vermiculite. The crushed corn stalks are 3-4 cm long.

[0029] The preparation method is the same as in Example 1.

Embodiment 3

[0031] The organic fertilizer provided by the invention is used to reduce the incidence of cucumber root-knot nematode, and its raw materials are as follows:

[0032] 40 kg of vermicompost, 30 kg of crushed corn stalks, 30 kg of sawdust, and 8 kg of vermiculite. The crushed corn stalks are 3-4 cm long. Example 2

[0033] The preparation method is the same as in Example 1.

Abstract

The invention provides an organic fertilizer for reducing morbidity of cucumber root-knot nematode. The organic fertilizer comprises the following raw material in weigh ratio: 35-40 of wormcast, 25-30 of smashed corn straw, 28-30 of sawdust and 8-10 of vermiculite. The preparation method comprises the following steps: fully and evenly mixing the smashed corn straw, the sawdust and the vermiculite which are weighed proportionally, and moistening with a proper amount of water so that the water content of the compositing material is 50-60%; piling up the corn straw, the sawdust, the vermiculite and the like in a plastic house or in the open air, and adding 3000-5000g of fermentation bacteria agent in each ton of material for fermentation; and fully and evenly mixing the completely fermented mixture of corn straw, sawdust and vermiculite with the weighed wormcast, smashing, drying and finally packaging. The organic fertilizer can be directly used as a base fertilizer for cultivating cucumbers, thereby effectively alleviating the harm of root-knot nematode. The morbidity is reduced by 79.4%, and the yield of the cucumber is improved by 34.4%.

Description

technical field [0001] The invention relates to an organic fertilizer formula and a preparation method for cucumber cultivation, in particular to an organic fertilizer formula and a preparation method that can reduce the incidence of cucumber root-knot nematodes, improve soil fertility, and increase cucumber yields, and belong to agricultural intensive production technology and plant field of disease prevention. Background technique [0002] Cucumber root-knot nematode is one of the most harmful soil-borne diseases in cucumber continuous cropping cultivation. Because of its complex pathogenesis, it has not been fully understood yet. It is generally believed that it is due to continuous planting of cucumbers and unreasonable fertilization management methods, resulting in soil nutrient imbalance, salt accumulation, and structural deterioration. Especially when the original microbial flora of the soil changes, the beneficial microorganisms in the soil are suppressed, and the h...
