Embodiment 1

[0029] Hybrid pennisetum ( Pennisetum americanum x P . purpureum ) cultivation method on saline-alkali soil, comprising the steps of:

[0030] (1) Treat the saline-alkali soil where hybrid pennisetum is planted

[0031] Land preparation for saline-alkali land: Loosen the soil at a depth of 50cm to make the soil clods finely broken and loose, and remove weeds, stones, etc.;

[0032] Open a strip-shaped planting ditch on the saline-alkali land, the distance between the ditch and the ditch is 50cm, each ditch is 18cm wide and 15cm deep;

[0033] (2), using cultivation substrate and treating saline-alkali soil

[0034] Sprinkle the peat soil with sulfur powder into the planting ditch of step (1), and cover it for about 2.5cm. The mixing ratio of sulfur powder and peat soil in the peat soil with sulfur powder is 5mg: 1000mg;

[0035] (3) Treatment of hybrid Pennisetum plants before planting

[0036] Select more than 5 months old, healthy, nearly mature whole plant...

Abstract

The invention discloses a method for cultivating hybrid pennisetum in saline-alkali soil, which includes the steps: treating hybrid pennisetum in the saline-alkali soil and a culture medium; treating plants before planting; planting; managing the hybrid pennisetum after planting; and the like. Ripe hybrid pennisetum can be obtained 6-6.5 months later. Using the method can increase the survival rate of the hybrid pennisetum in the saline-alkali soil by more than 15%, and increase growth of the hybrid pennisetum in the saline-alkali soil by more than 20%.

Description

technical field [0001] The invention relates to a cultivation method of hybrid pennisetum, in particular to a cultivation method of hybrid pennisetum on saline-alkali soil. Background technique [0002] Pennisetum hybrids (hereinafter referred to as hybrids) are Pennisetum genus ( pennisetun ) in diploid Pennisetum americana (also known as pearl millet, English name pearl or bulrush; scientific name P. americanum (L)K. Schum= P . typhoidum = P . gloucum ) and tetraploid elephant grass (also known as purple pennisetum, British name napier grass or elephant grass; scientific name P. purpureum The interspecific hybridization of Schum) produces triploid hybrids, whose progeny are not fruitful, and are usually propagated or asexually propagated with the first generation of hybrid seeds in production. [0003] In the early days, M.E.AKEN'OVA and others published "Seed Production of F_1 Generation Cultivated Forage Grass Hybrids of Purple Pennisetum and American Pennisetu...
