Castor oil plant and polygonatum odoratum interplanting technique

Abstract

The invention discloses a castor oil plant and polygonatum odoratum interplanting technique and relates to the technical field of agricultural planting. The planting process of the technique comprises the following: A, a step of land preparation; B, a step of interplanting and cultivation, which is to plant polygonatum odoratum after furrowing and applying base fertilizer and to plant castor-oil plants after digging holes and applying base fertilizer; C, a step of field management, which comprises field management of polygonatum odoratum in four seasons and field management of the castor oil plant; and D, a step of harvesting, which is to harvest polygonatum odoratum fruit and castor beans respectively. The technique has the characteristics of high land comprehensive utilization rate, high economic benefit, high product quality and the like, is suitable for cultivating castor oil plants and polygonatum odoratum at different latitudes and is suitable for planting castor oil plants and polygonatum odoratum in arid soil in hill areas and in fields in arid areas.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to an interplanting technology of castor and Polygonatum odoratum. Background technique [0002] Castor [Ricinus communis L.] is an economical oil crop with the characteristics of stem height, sun-loving, and drought tolerance. Its main growth space is on the ground and upwards, and it needs more light during the growth process. Belongs to strong light plants. Polygonatum odoratum (Mill.) Druce is a traditional Chinese medicinal material with short stems and shade tolerance. Its main growth space is underground, and the growth space on the ground is limited, and it does not need strong light during the growth process. Direct sunlight, therefore, when it is planted alone, it is necessary to use a shade grid to block the sun in the high temperature season. [0003] In the prior art, both castor and Polygonatum are planted separately. Although this planting method has m...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, both castor and Polygonatum are planted separately. Although this planting method has many advantages such as single management, it also has many shortcomings: one is that due to the large canopy of castor, it needs to take up more space. Land and space, therefore, the comprehensive utilization rate of the land is low, and the economic benefit is poor; the second is that the difference in light demand of plants is not fully utilized, and the utilization rate of sunlight resources is low; the third is that Polygonatum odoratum is planted and grown During the process, there will be many diseases and insect pests such as gray spot, rust, and grub pests, which need to be controlled by using a variety of pesticides, which will affect the quality of Polygonatum odoratum products
