Planting technology and mu income of rhubarb

Planting techniques: rhubarb is a deep-rooted crop that likes cold and heat, so it is necessary to choose a mountain area with an altitude of about 1700m, during which it can be rotated with corn, leek and soybean crops, and before planting, it is necessary to cultivate the land deeply and then apply basic fertilizer. Seeds can be propagated by seeds or seed buds, and new seeds should be selected, sowing 5-6 seeds per hole in spring or autumn and covering soil, and seed bud propagation is suitable for small area cultivation. Mu income: the average income per mu is about 4000-6000 yuan.

I. planting techniques of rhubarb

1. Select the place

The planting technology of rhubarb first needs to pay attention to the selection of plots and the arrangement of plots. Rhubarb's habit is that it likes cold and is afraid of heat. Therefore, it is generally a mountain area with a certain elevation in life (about 1700 meters above sea level).

Rhubarb is a deep-rooted plant, and its main root can even reach about 40cm below the soil layer. Rhubarb needs to go through a 4-5-year rotation cycle of discontinuous planting when planting rhubarb. But he can make full use of land resources by rotating potatoes, rape, legumes and so on.

Some plants such as corn, leek and soybeans can be planted in the first year after planting.

2. Land preparation

After selecting a good plot, the whole plot needs to be cultivated deeply, and the depth of soil ploughing is above 30cm. Generally, about 50 tons of rotten barnyard manure or compost and soil ash are applied per hectare, and deeply buried in the soil as basic fertilizer.

3. Soil requirements

The cultivation of rhubarb is not very strict on soil quality, and it is most suitable to be planted in loam rich in humus brown soil and sandy loam. it is more suitable to grow in suitable drainage, deep soil layer, rich in humus brown soil and sandy soil. in addition, it should be noted that clay is not suitable for the growth of rhubarb.

Second, the mu income of rhubarb

If it is sold at an average price of 24 yuan per kilogram, if farmers plant, excluding the cost of seedlings per mu, chemical fertilizer, cultivated land, agricultural medicine, mining and excavation, manual peeling and peeling, drying or drying, the total planting cost per mu is about 3700 yuan. The average yield per mu is about 6000 yuan.

If the cooperative planting, the cost will also be higher, about 5500 of the cost, the total average yield per mu of about 4000 yuan.

III. Propagation techniques of rhubarb

1. Seed propagation

Seed propagation generally adopts two ways: direct seeding and seedling transplanting. The use of seeds is the most important way to plant and cultivate rhubarb, but it should be noted that the life span of rhubarb seeds is only one year, and old plants should not be used for reproduction.

The sowing time of rhubarb is generally in the early ten days of spring or autumn, the row spacing of direct sowing is 70cm*50cm, the sowing method is hole sowing, the depth of hole sowing is about 3cm, and 5-6 seeds can be sowed in each hole, and the thickness of covering soil is about 2cm, so seedling transplanting is not suitable in the dry areas of Beijing in spring.

2. Seed bud propagation

The reproduction of seed buds is more suitable for cultivation with relatively small planting area. When harvesting rhubarb, cut off the rhizome around the mother plant with high yield, exuberant growth, and no diseases and insect pests. Each trimmed rhizome needs to have 3-4 bud eyes, use plant ash to smear the fish wound or separate seed buds, and then plant on the prepared seedbed.
