Problems solved by technology

Because Jatropha curcas is a tall shrub and arbor species, the understory area between the row spacing of cultivated plants is often just growing weeds, which not only brings too much weeding cost for field management and maintenance, but also the land is not fully utilized, and the production efficiency is reduced. Can not be brought into play efficiently, for this reason, the inventor proposes the method for interplanting vetiver between Jatropha curcas according to the biological characteristics of two different family plants

Embodiment 1

[0023] Follow the steps below

[0024] 1. Seedling raising: In March, open a 5cm-deep shallow ditch on the surface of the well-arranged seedling raising field, and the distance between the ditch (row spacing) is 20cm. In the shallow ditch, jatropha seeds are sown at a distance of 10cm. , Seedling management and care for transplantation for 3 months. The new plants tilled in the vetiver seedling fields were excavated as seedlings.

[0025] 2. Preparation for interplanting: Open a 50cm-wide flat strip along the contour line of the planting plot. The distance between the centers of two adjacent strips is 300cm as the row spacing. Dig 40×40×40cm on the strip-shaped flat ground at a plant spacing of 200cm. The jatropha planting pond, leave 10cm of loose soil at the bottom of the pond; dig two vetiver planting holes of 5×5×5cm between the jatropha plants at a distance of 50cm.

[0026] 3. Interplanting: Jatropha curcas is planted in a pond of 40×40×40cm, and the planting depth is ...

Embodiment 2 and Embodiment 3

[0034] Embodiment 2 and embodiment 3: except that the amount of basal fertilizer applied and the amount of topdressing are different, and in the amount of basal fertilizer and in the topdressing, the mass ratio of compound fertilizer and superphosphate is different, all the other operating methods are the same as in Example 1, and will not be repeated. . See Table 1 for the differences.

[0035] According to the above examples, the vetiver was mowed stably in the second year of growth. Through yield measurement, an average of 3,790 kilograms of vetiver green forage grass was harvested per mu. Calculated at the price of 0.2 yuan per kilogram, the annual economic income per mu will be increased. 758 yuan.

Abstract

The invention provides a method for interplanting vetiver grass and barbadosnut, and belongs to the technical field of crop planting. The method comprises the following steps of culturing seedlings, preparing an interplanting land, interplanting, managing and protecting, harvesting seeds, and cutting forage grass, wherein the interplanting land is developed to be a strip-shaped flat land being 50cm in width; the central spacing between the strips is the line spacing and is 300cm; barbadosnut planting embankments are excavated based on the planting distance of 200cm; two vetiver grass planting cavities are excavated between barbadosnut seedlings based on the planting distance of 50cm; base fertilizer composed of compound fertilizer and calcium superphosphate in ratio of 1: 2-5 is applied during planting barbadosnut seedlings; 2 to 3 tillers are planted in each cavity of vetiver grass; additional fertilizer is applied 90 days after barbadosnut seedlings are fixed in planting; additional fertilizer is applied to vetiver grass about 45 days after vetiver grass grows; the additional fertilizers are the same as the base fertilizers. With the adoption of the method, the biodiesel can be developed, the utilization rate of idle lands between barbadosnut seedlings can be raised, the water and soil loss of a new barbadosnut planting land can be effectively controlled, 3,500 to 4,000kg fresh vetiver grass leaves can be averagely harvested from land per mu and used as forage grass, and thus more 700 to 800 Yuan economic income is brought.

Description

Technical field [0001] The present invention involves the field of forest farmers planting technology, and specifically involves a method of planting grass and mad trees. Background technique [0002] Ma Crazy Tree ( Jatropha Curcas ) It is a kind of perennial and multi -purpose tree species resistant to drought -resistant and barren. It is widely distributed in tropical or subtropical regions. It is mainly produced in the Americas and Africa tropical.my country is mainly distributed in Yunnan, Sichuan, Guangxi, Guangdong, Hainan and other places, with the most Yunnan and Sichuan.In addition to planting hemp crazy trees, it can increase vegetation and improve the ecological environment.Its seeds and tree juice have widely used in pharmaceutical, chemical, protein feed.Especially the crude fat mixture obtained from the seeds can obtain ideal environmental mechanical fuel after further chemical transformation, called biological diesel. [0003] Grassy (Grassy ( Vetiveria zizanioabl...
