Soilless cultivation techniques of Rabdosia angustifolia

First of all, prepare the cultivation trough, which is 30cm high and 50cm wide. Then use the cinder or slag in daily life to mix chicken manure, ternary compound fertilizer and organic fertilizer to mix the substrate, which can be packed into the trough when it is accumulated and mature. Before sowing, treat the seeds and soak them in warm water for half an hour. The row spacing of the control plant is about 15 × 15cm. Base fertilizer should be applied once after harvest to ensure the nutrients needed for its growth.

1. Planting preparation

Soilless cultivation is different from the traditional planting method, it needs special planting equipment-cultivation trough, which can be purchased directly or built on its own. Generally, the cultivation trough is high 30cm and wide 50cm. Another important thing is the deployment of the cultivation substrate, which can be mixed with daily cinder or slag mixed with chicken manure, ternary compound fertilizer and organic fertilizer. When installing the trough, the bottom of the trough is now covered with a layer of 5cm thick sand, and then fill in the prepared matrix, fill the matrix, be careful not to be too tight, be of the same thickness, pour thoroughly with water, wait for the water to seep completely, and cover the film for half a month, then you can plant.

2. Sowing and raising seedlings

In order to ensure the germination rate before sowing, the seeds were treated first, soaked in warm water within 60 degrees for half an hour, then soaked in clean water for 24 hours, and then wrapped in a wet gauze to accelerate germination in the greenhouse. Open and rinse with warm water once a day, wait for the seeds to whiten and then sow. Select the matrix with good permeability when sowing, cover a layer of sand and gravel after sowing, then cover with film to keep warm and moisturizing, maintain the temperature at about 25 degrees Celsius, about half a month, and remove the film in time after emergence to increase permeability. When the seedlings grow to 12cm or so, they can be planted.

3. Colonization

The row spacing of the planting control plant is about 15 × 15cm. When planting, we should pay attention to the time and climate, usually in the afternoon, remember when the sun is maximum at noon and the cloudy and rainy weather. Before planting, the cultivation substrate will be watered once, and after the water permeates, the seedlings will be planted, and the 2-3 stem nodes of the seedlings can be buried deeply.

4. Management

Asparagus is a vegetable that can be harvested many times a year. In order to make it grow rapidly after harvest, it is generally necessary to apply base fertilizer after harvest to ensure the nutrients needed for its growth. Urea can be applied after harvest, and there is a large amount of water storage when planting asparagus, so water should be watered frequently and watered thoroughly. Soilless cultivation of asparagus has fewer diseases and insect pests, but we should still pay attention to pest control.
