Embodiment 1

[0018] (1) Seedling substrate:

[0019] a. Measure the organic matrix, cow dung, and plant ash according to the volume ratio of 8:2:1, and pour them into the mixer / machine;

[0020] b. 2.1-2.5kg / m of urea weighed by weight 3 , ammonium dihydrogen phosphate 1.5-1.8kg / m 3 Grind into powder, along with quicklime 1.5-1.8 kg / m 3 Add to blender / machine;

[0021] c. Then chlorothalonil 75% wettable powder by 1.2-1.5kg / m 3 Add the amount to the blender / machine;

[0022] d. Turn on the machine, mix evenly, and obtain the seedling raising substrate for preventing and controlling Chinese cabbage clubroot after subpackaging.

[0023] The organic matrix is ​​humus or peat or coconut bran or bagasse or sawdust; wherein: use humus as the organic matrix, pass through a sieve with an aperture of 2-3mm before use, and remove large branches or stones; Crush and pass through a sieve with an aperture of 2-3mm; before use, coconut peat, bagasse and sawdust should be piled into a large steam...

Embodiment 2

[0032] (1) Seedling raising substrate is the same as that in Example 1.

[0033] (2) Plug seedlings:

[0034] 100 holes of PE trays are filled with the seedling raising substrate obtained in step (1). Water thoroughly, the substrate falls, sow the baby cabbage seeds of the susceptible species of clubroot on the substrate, 2 seeds per hole, cover the seedling cultivation substrate obtained in the step of 0.2-0.5cm (1), and then cover with a white film. Seedlings emerged in 3 days, and the seedlings emerged neatly. Remove the film and replenish water once a day on sunny days. 25-30 days into seedlings. Adult seedlings have no clubroot, well-developed root system, seedling height of 4-6cm, and 5-6 true leaves.

[0035] (3) Transplanting:

[0036] Stop watering 2 days before transplanting. When transplanting, the seedlings are pulled out from the hole tray in lumps, and the planting water is poured thoroughly first, and then the seedlings are settled and sealed.

[0037] (4)...

Abstract

The invention discloses a seedling substrate for preventing and controlling cabbage clubroot, and belongs to the technical field of vegetable culture. The seedling substrate is obtained by the steps: a, measuring organic substrates (humic soil or turf or coco coir or bagasse or wood dust), cow dung and plant ash according to the volume ratio of 8:2:1 and pouring the organic substrates, the cow dung and the plant ash into a stirrer / stirring machine; b, grinding weighed 2.1-2.5kg / m<3> of urea and 1.5-1.8kg / m<3> of ammonium dihydrogen phosphate into powder, adding the powder along with 1.5-1.8kg / m<3> of calcined lime into the stirrer / stirring machine; c, adding 1.2-1.5kg / m<3> of wettable powder with 75% of chlorothalonil into the stirrer / stirring machine; and d, starting the machine, uniformly stirring the powder and sub-packaging the powder. The seedling substrate has the advantages that vegetable shoots are fine in quality, the clubroot is avoided, diseases are relieved after planting, control effect is long, the seedling substrate is not limited by physiological race, and environmental side effects are avoided.

Description

Technical field: [0001] The invention relates to a seedling raising substrate for preventing and controlling Chinese cabbage clubroot, belonging to the technical field of vegetable cultivation. Background technique: [0002] Clubroot of Chinese cabbage is caused by Plasmodiophora brassicae Woronin and is a worldwide soil-borne disease. Clubroot is an obligate parasite that infects more than 100 species and varieties of wild and cultivated Brassicaceae. The fungus exists in the form of dormant spores in the soil without a suitable host, and the survival time can be as long as 15 years. Once a suitable host is encountered, the dormant spores germinate and proliferate immediately and infect the root hairs, forming a multinucleated plasmodium. The plasmodium splits to form secondary zoospores and migrates to the cortex of the root, inducing abnormal growth of cells, forming a large number of lumps, inhibiting the absorption of water and nutrients, resulting in weakened growth ...
