Cultivation techniques of Rhododendron chinense

Red Phoenix is a kind of wild vegetable that people used to pick and eat in the past, also known as Buxue grass, with the function of tonifying blood, mainly eating its aboveground part. Wild vegetables are delicious, but now people recognize their nutritional value and begin to cultivate and supply them themselves. Cultivation has its own unique process and problems that should be paid attention to. Now let's introduce its cultivation techniques.

1. Planting time

The general time is in spring and autumn, the four seasons can be picked, the summer growth is the most prosperous, can be picked many times. In general, the most commonly used type of propagation prevention is cutting propagation, because of its strong germination, the use of cutting method is the most suitable.

2. Mother plant selection.

Generally, the plants with good growth, normal leaf color, broad leaves, strong root growth and upright stem should be selected as the cutting mother plant. It is probably possible to take two or three branches from each mother plant, so that the mother plant can continue to grow, basically normal. However, if you do not want to keep the mother plant, you can also press the whole mother plant for strip propagation, and the number of seedlings will be more. The specific dosage depends on the planting area.

3. Land preparation

Choose more open, sunny, leeward deep fertile soil to plant, generally sandy loam. Then the soil will be turned over deeply, and the whole field will be sprinkled with fertilizer and mixed with the soil. Ridge line, row width is about 30 cm, can not afford ridge surface planting, leaving ditch about 15 cm for people to walk, depth of about 20 cm, ditch depth good drainage, but ridge narrow ditch is too deep and easy to cross ridges after heavy rain. And then dry the fields for a week.

4. Planting preparation

Can first take the side branches from the mother plant, cut off the top delicate part, and then cut the lower end into an oblique cut, soak alcohol with rooting powder solution, do not mix with water, water can not play the role of rooting powder. Or ground to cut off the mother plant, cut off the aging part of the lower end and the young part of the upper end, cut the middle stem into centimeter segments and then soak in rooting powder for about half an hour.

5. Planting

Take out the soaked stem, do not take root in the seedling bed, directly plant in the field, the plant grows first and then calculate the row spacing, generally the plant spacing is about 25 cm, the row spacing is no longer considered because of the good ridge line. First pour water on the ridge and then dig a small hole, each pit oblique insert two or three plants to ensure that the soil cover near the survival pressure is tight. About 20,000 to 30,000 seedlings should be planted per mu. After covering the sunshade net, watering and moisturizing every day, about half a month later to observe the long root condition, we can remove the sunshade net and pour less water.

The cultivation of red Phoenix cabbage is such a general process, in which there may be some detailed problems, which will be used in actual planting. Everything in production naturally needs a lot of attention. Here we will only introduce some specific planting methods.
