Embodiment 1

[0018] A high-yield cultivation method for kale, comprising the following steps:

[0019] 1. Sowing: In late summer and early autumn, select a flat land as a seedbed, spread a layer of substrate evenly on the seedbed, and use plug trays to sow seedlings after watering;

[0020] 2. Transplanting and planting: one month after sowing, when the kale seedlings grow four leaves and one heart, they are planted in the field, and the decomposed human and animal manure is applied to carry out conventional field management;

[0021] 3. Cutting the top: when the kale bolts after transplanting and planting for half a year, cut off the stalk and the upper leaves, and keep the bottom height of the kale at 20cm;

[0022] 4. Spraying of plants after top cutting: use 500 times dilution of 15% paclobutrazol wettable powder to spray once on the plants after top cutting.

Embodiment 2

[0024] A high-yield cultivation method for kale, comprising the following steps:

[0025] 1. Sowing: In late summer and autumn, select flat land as a seedbed, spread a layer of substrate evenly on the seedbed, and use plugs to sow seedlings after watering;

[0026] 2. Transplanting and planting: One month after sowing, when the kale seedlings grow four leaves and one heart, they are planted in the field, and decomposed human and animal manure is applied, and conventional field management is carried out;

[0027] 3. Cut the top: half a year after transplanting and planting, when the kale is bolting, cut off the stalk and the upper leaves, and keep the bottom height of the kale at 18cm;

[0028] 4. Spray the plants after the top is cut, and spray once on the plants after the top is cut.

[0029] The spraying of the plant after the top cutting is to use 500 times dilution of 10% paclobutrazol wettable powder.

Embodiment 3

[0031] A high-yield cultivation method for kale, comprising the following steps:

[0032] 1. Sowing: In late summer and autumn, select flat land as a seedbed, spread a layer of substrate evenly on the seedbed, and use plugs to sow seedlings after watering;

[0033] 2. Transplanting and planting: One month after sowing, when the kale seedlings grow four leaves and one heart, they are planted in the field, and decomposed human and animal manure is applied, and conventional field management is carried out;

[0034] 3. Cut the top: half a year after transplanting and planting, when the kale is bolting, cut off the stalk and the upper leaves, and keep the bottom height of the kale at 22cm;

[0035] 4. Spray the plants after the top is cut, and spray once on the plants after the top is cut.

[0036] The spraying of the plant after the top cutting is to use 500 times dilution of 20% paclobutrazol wettable powder.

Abstract

The invention discloses a high-yield cultivation method of kale. The method comprises the following steps: sowing: selecting a flat site as a seedbed in the late summer and early autumn, uniformly laying a layer of substrate on the seedbed, watering, carrying out hole tray sowing and seedling raising, and transplanting and planting in the field: one month after sowing, when kale seedlings grow four leaves and a core, planting the kale seedlings in the field, applying decomposed human and livestock manure, and carrying out routine field management; cutting off tops: six months after transplanting and field planting, when the kale starts bolting, cutting off bolting stems and top leaves, maintaining the height of the bottom of kale at 18-22cm; spraying mist to the plants after cutting off tops, spraying mist to the plants once after aligning and cutting off tops. As for the high-yield cultivation method of kale, the bolting stems and top leaves are removed when the kale starts bolting, 300-fold diluted Bacillus thuringiensis solution is sprayed directly onto the plants and foliar fertilizer is topdressed. Thus, a lot of primary branches grow in the leaf axils of the kale, the harvesting period is effectively prolonged and can be extended to early May, and the yield is increased.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a high-yield cultivation method of kale. Background technique [0002] Kale, also known as cauliflower cabbage, leaf peony, and colorful cabbage, is a biennial herb of the Brassicaceae Brassica genus. Native to the Mediterranean coast, it is planted more in Britain, Holland, Germany, Japan and the United States, and is widely cultivated all over the world. my country began to introduce and cultivate it in the 1990s. It is more common in Jiangnan regions such as Shanghai and Hangzhou. It is gradually introduced in North China and Northwest China, and the Northeast region is still in the stage of introduction experiments. [0003] Kale, which is rich in calcium and cellulose, is divided into green and purple. It is an ideal high-quality vegetable in late autumn, early winter and early spring. The current kale is lodging due to bolting and growing taller from January to the end of Mar...
