The invention belongs to the field of agricultural plant breeding and discloses a method for increasing the hybrid seed production efficiency of self-incompatibility gramineous plants. The method includes the steps of firstly, preparing materials, to be more specific, planting Chinese silvergrass seedlings or rhizomes in pots; secondly, culturing plants, to be more specific, culturing the pot-cultured Chinese silvergrass under 24 DEG C and in light for 16 hours / under 18 DEG C and in darkness for 8 hours, watering once each day until the soil is completely wetted, and supplementing a Hoagland plant nutrient solution three times every week; thirdly, pruning the plants, to be more specific, timely cutting off tillers after flowering each day in the flowering period to promote the plants to constantly growth new tillers and achieve earing and flowering, cutting of the tillers after flowering, and repeating to achieve annual flowering; fourthly, using dark induction to induce inflorescencespikelet to disperse pollen, to be more specific, arranging inflorescence about to enter the vigorous flowering period, and inducing the plants under room temperature in complete darkness for 8-12 hours; fifthly, collecting pollen, to be more specific, shaking the inflorescence to collect the pollen after most spikelet on the inflorescence exposes anther after the dark induction. The method is simple, efficient and beneficial to the efficiency of Chinese silvergrass hybrid breeding and genetic researches.

The invention relates to a potted plant technique based efficient breeding method for salix brachypoda cutting in degraded inland saline marsh wetlands with an aim to mainly solve problems the salix brachypoda cutting in the degraded inland saline marsh wetland is low in survival rate and slow in restoration. The method specifically includes the steps of 1), seed selection and storage; 2), land selection; 3), soil unloading and potting; 4), cutting; 5), hydrologic management; 6), transplantation. The method has the advantages that raw materials are easy to obtain, cost is low, operation is simple and easy to implement, and centralized management is facilitated; ecological laws are obeyed, and environmental adaptabilities of wetland plants are fully considered; restoration of an inland saline-alkali marsh wetland ecosystem is benefited; the survival rate of salix brachypoda can reach more than 97%, and biodiversity of wetlands is increased.
