Quick-growing high-yield and high-efficiency carbon-catching cultivation method of pennisetum alopecuroides and pennisetum purpureum schumach

Abstract

The invention discloses a quick-growing high-yield and high-efficiency carbon-catching cultivation method of pennisetum alopecuroides and pennisetum purpureum schumach. According to the method, vegetative propagation is conducted on the pennisetum alopecuroides, the pennisetum purpureum schumach and breeds cultivated after the pennisetum alopecuroides and the pennisetum purpureum schumach are crossed through stems, wherein the breeds comprise pennisetum hydridum, pennisetum purpureum schum ev, crossed pennisetum alopecuroides and the like. Exclusive quick propagation, high-yield cultivation, multi-time harvesting and scientific burying technologies are adopted to achieve quick growing, high yields and high-efficiency carbon sequestration burying of the pennisetum alopecuroides, the pennisetum purpureum schumach and crossed breeds of the pennisetum alopecuroides and the pennisetum purpureum schumach, and accordingly the artificial propagation, cultivation and carbon sequestration burying method of the pennisetum alopecuroides and the pennisetum purpureum schumach is created. By utilizing the method, fresh products of the pennisetum alopecuroides or the pennisetum purpureum schumach can be harvested with an amount of 75-150t / hm<2> for one year, and a maximum amount of 450t / hm<2>. The method ensures that planting, burying, and large-sale and industrialized production of the pennisetum alopecuroides, the pennisetum purpureum schumach and crossed breeds of the pennisetum alopecuroides and the pennisetum purpureum schumach are possible to happen, achieves negative increase of discharge capacity of CO2 in the atmosphere, and releases greenhouse effects of the atmosphere.

Description

technical field [0001] The technical field of plant cultivation of the present invention relates to a fast-growing, high-yield and high-efficiency carbon capture cultivation method of Pennisetum and Elephant Grass. Background technique [0002] Pennisetum alopecuroides (L) Spreng is a perennial herbaceous plant of the family Gramineae. It is distributed both at home and abroad. It has strong adaptability to soil, is resistant to slight alkalinity, and is also resistant to drought and poor soil. Pennisetum is strong in nature, strong in germination, easy to cultivate, does not require high water and fertilizer, and rarely suffers from diseases and insect pests. Perennial Pennisetum has a well-developed root system and has good soil-fixing and slope protection functions. [0003] Elephant grass (Pennisetum purpureum Schum), also known as purple pennisetum, is a perennial herbaceous plant of the genus Pennisetum in the Gramineae family. Native to Africa, the plant is tall, w...
