Detailed Explanation of Rhubarb Planting Technology and Per-Mu Income Analysis

AbstractPlanting technology: Rhubarb is a deep-rooted crop that prefers cold and fears heat. It is necessary to choose mountainous areas at an altitude of about 1700 m. During this period, it can be rotated with corn, chives, and soybean crops. Before planting, the plot needs to be deeply plowed and carefully prepared, and then base fertilizer should be applied. It can be propagated by seeds or by daughter buds. For seed propagation, new seeds must be selected, and 5-6 seeds should be sown per hole in spring or autumn and covered with soil. Daughter bud propagation is suitable for small-area cultivation. Per-mu income: The average income per mu is about 4000-6000 yuan.

I. Rhubarb Planting Technology

1. Land selection

The first thing to note in rhubarb planting technology is the selection and preparation of the plot. Rhubarb's habit is that it prefers cold and fears heat. Therefore, it generally grows in mountainous areas with a certain altitude (an altitude of about 1700 m).

Rhubarb is a deep-rooted plant, and its main root can even reach about 40 cm below the soil layer. When planting rhubarb, it needs to go through a 4-to-5-year rotation cycle of non-continuous planting. However, it can make full use of land resources by rotating with potatoes, rapeseed, and leguminous plants, etc.

In the first year after planting, some plants such as corn, chives, and soybeans can be planted in the gaps.

2. Land preparation

After selecting the plot, the entire plot needs to be deeply plowed and carefully prepared. The soil cultivation depth is more than 30 cm. Generally, about 50 tons of decomposed barnyard manure or compost and wood ash are applied per hectare, and deeply plowed and buried in the soil as base fertilizer.

3. Soil requirements

Rhubarb cultivation does not have very strict requirements for soil quality. It is most suitable for planting in humus-rich brown soil and sandy loam. It is more suitable for growing in soil with suitable drainage, relatively deep soil layers, rich humus brown soil, and sandy soil. In addition, it should be noted that clay soil is not very suitable for rhubarb growth.

II. Per-Mu Income of Rhubarb

If sold at an average price of 24 yuan/kg for general dry goods, for farmers planting it, after deducting costs such as seedling cost of 2500 yuan/mu, chemical fertilizer 300 yuan/mu, ploughing 100 yuan/mu, manual planting fee 200 yuan/mu, pesticide fee 300 yuan/mu, harvesting labor fee 100 yuan/mu, manual sorting, peeling, and topping fee 100 yuan/mu, and drying or oven drying 100 yuan/mu, the total planting cost per mu is about 3700 yuan, and the average income per mu can be about 6000 yuan.

For cooperative planting, the cost will also be higher, about 5500 yuan, and the total average income per mu is about 4000 yuan.

III. Rhubarb Propagation Technology

1. Seed propagation

Seed propagation generally adopts two methods: direct sowing and seedling raising followed by transplanting. Using seeds is the most important method for planting and cultivating rhubarb, but in planting it should be noted that the lifespan of rhubarb seeds is only one year, and old seeds must absolutely not be used for propagation.

The sowing time of rhubarb is generally in the first ten days of spring or the first ten days of autumn. The row spacing for direct sowing is 70 cm * 50 cm. The sowing method used is hole sowing, and the depth of hole sowing is about 3 cm. Also, 5-6 seeds can be sown in each hole, and the soil covering thickness is about 2 cm. When raising seedlings and transplanting, it is not very suitable in the arid areas of Beijing in spring.

2. Daughter bud propagation

Daughter bud propagation is more suitable for cultivation with a relatively small planting area. When harvesting rhubarb, cut off and select the rhizomes around the mother plant from plants with high yield, relatively vigorous growth, and no pests or diseases. Each trimmed rhizome needs to have 3-4 bud eyes. Apply plant ash to the wounds or the separated daughter buds, and then plant them on the prepared seedbed.
