Embodiment 1

[0027] A. Use mature sweet elephant grass stem nodes as seedlings, adopt asexual cultivation method, and use stem node cuttings or rhizome ramets transplanting methods to rapidly multiply; when the soil, climate and management conditions are good, directly in the field Plant;

[0028] A1. Seedling time: in the north, seedlings are raised from April to October; in the south, seedlings are raised throughout the year;

[0029] A2, seed node preparation: select the sweet elephant grass stem node of the stem node breasth diameter more than 3 cm, and the spore germination fat person to make the seedling, first tear off the leaves that wrap the axillary buds, cut into small sections with a knife, the section surface of the knife edge should be an inclined plane, One node is reserved for each segment, and there should be an axillary bud on each node. The upper part of the bud eye is kept short and the lower part is long;

[0030] In order to improve the survival rate, conditional roo...

Abstract

The invention discloses a cultivation method of sweet elephant grass. The cultivation method comprises adopting mature sweet elephant grass stem sections as seedlings, performing cultivation in an asexual mode and performing rapid expanding propagation through stem section cutting or root stock plant division transplanting; directly planting on the field when the soil, climate and management conditions are good; performing watering every day in the seedling growing period to maintain the moist soil, performing once topdressing of organic fertilizer and compound fertilizer until plants are grown to 60 cm height and combining with soil loosening to perform once watering and topdressing in two days after every time harvest; harvesting which comprises performing interlacing harvest from spring to early summer, wherein the harvest height is 2.5 to 3.5 m. According to the cultivation method of the sweet elephant grass, different operation processes are implemented according to the four seasons and accordingly the yield per mu of the sweet elephant grass can be improved by 60 to 70 tons, the quality of the sweet elephant grass is high, the requirements of the livestock and poultry industry can be met, the economic benefit is improved, the investment return period is shortened, and the agricultural sustainable development is implemented.

Description

technical field [0001] The invention relates to the technical field of agricultural production systems, in particular to a cultivation and planting method of sweet elephant grass. Background technique [0002] High-quality forage—Sweet elephant grass belongs to the genus Pennisetum of the Gramineae family. It is a new type of high-protein and high-yield forage widely cultivated in tropical and subtropical regions. It is an important green feed for livestock and poultry in southern China. It can be planted continuously for one year. It takes 7 or 8 years to harvest, and it can be harvested all year round in the tropical areas of Guangdong and Guangxi. It has the characteristics of strong adaptability, fast reproduction, high yield, good quality, and long utilization period. It can be harvested 6-8 times a year. At present, domestic statistics report that the yield per mu is about 15 tons, and the highest can reach 30 tons. [0003] At present, the planting of sweet elephant ...
