Sugar-cane tree-seedling strong seedling cultivation method

Abstract

The invention relates to a sugar cane seedling plant and sound seedling cultivation method, which is provided aiming at that the sugar cane hybrid seed is tiny, and has comparatively light thousand seed weight, less nutrient content and villus; when cultivating the seedling, the seed is susceptible to fungi and has low germination rate, the seedling is weak and susceptible to diseases, and so on. The goal of cultivating sugar cane seedling vigorous and healthy plants is realized through the implementation of eight technical steps of the improvement of seedbed matrix, the improvement of seedbed structure, the seed disinfection and sparse seeding, the control of temperature and preservation of humidity to promote germination, the control of temperature and preservation of humidity to promote growth, timely fertilizer application, shading and seedling training, defoliation and chemical control to promote robustness. The seedling plant cultivated by applying the method has flourishing root system, dark leaf color, and vigorous and healthy plants, and is easy to be transplanted in fields; and the field transplantation survival rate of the seedling plant under the same conditions is raised by 10 to 15 percentage points.

Description

Technical field: [0001] The invention relates to a method for cultivating strong seedlings of sugarcane seedlings. Background technique: [0002] Sugarcane is an important sugar crop in my country, and improved varieties of sugarcane contribute more than 60% to the sucrose industry. At present, the new sugarcane varieties cultivated in my country are mainly screened by interspecific and interhybrid hybrid seeds. However, the hybrid seeds of sugarcane are small and contain few nutrients, so they cannot be directly sown in the field, and seedlings must be raised first. And because the thousand-grain weight of sugarcane seeds is lighter, has fluff and less nutrients, it brings difficulties to the cultivation of seedlings. The use of conventional seedling raising methods often leads to the seeds being susceptible to mold, low emergence rate, weak seedlings, susceptible to disease and death. Invention content: [0003] The purpose of the present invention is to provide a meth...
