Sand storage and germination acceleration method of xanthoceras sorbifolia seeds

Abstract

The invention discloses a sand storage and germination acceleration method of xanthoceras sorbifolia seeds. The method comprises the steps as follows: (1) seed treatment: seeds are disinfected with 0.5% potassium permanganate for 2 h, a medicine liquid is drained, the seeds are sealed in a container for 30 min, washed repeatedly with clear water, soaked in clear water for 120 h and then subjected to sand storage; (2) sand storage treatment: sand storage treatment is performed in early December and continued for 4-6 months, the moisture content of river sand is about 60%, the prepared seeds are placed on a sand bed about 5 cm thick, the seeds are covered with river sand about 50 cm thick, and the river sand is covered with straw mats; (3) germination acceleration treatment: one week before seeding, the seeds are taken out and the river sand is washed away. The seeds are heated with hot water at 60 DEG C, soaked for 24 h after being cooled to the room temperature, fished out and uniformly mixed with the river sand in the ratio of 1: 3, the seeds are covered with straw mats, water spraying is performed for germination acceleration, and seeding can be performed when white kernels are exposed.

Description

technical field [0001] The invention relates to the technical field of seedling raising and accelerating germination methods, in particular to a sand storage method for accelerating germination of sorbifolia seeds. Background technique [0002] Xinguo is a deciduous shrub or small tree belonging to Sapindaceae. It has strong stress resistance and is not strict on soil. It can grow on sandy soil and saline-alkali soil. It is an important landscaping tree species for improving the ecological environment. However, the seed coats of X. sorbifolium seeds are hard and poor in water permeability, and the kernels contain abscisic acid to inhibit germination. The seeds must be treated before sowing, otherwise it is easy to cause uneven emergence or non-germination after sowing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that is simple, easy to operate, greatly improves the germination rate and emergence unif...
