Embodiment
[0145] From 2007 to 2011, the experimental field of Chifeng Academy of Forestry was used to test the seedling raising method of sorbifolium mulberry. The technical measures adopted are as follows:
[0146] 1 Seedling site selection and site preparation
[0147] 1.1 Selection of seedling sites
[0148] The terrain is flat, the soil is fertile, the sunlight is sufficient, the soil layer is deep, the irrigation is convenient, the drainage is good, the ph value is 7.0-8.0, and there is no heavy cropping.
[0149] land preparation
[0150] In the fall of the previous year, plow 25cm to 30cm deep, rake it in spring, and fill the bottom with water.
[0151] Fertilize
[0152] Spread 2,000 to 3,000 kilograms of farmyard manure per mu, combined with spring plowing, harrowing, and leveling.
[0153] Make a ridge
[0154] Mechanically make a large ridge, with a ridge top width of 40-60 cm and a height of 15-20 cm. The sowing belt can be sown in 2 or 4 rows. The watering and operatio...

Abstract
A mulch sowing and seedling raising method for Xanthoceras sorbifolia comprises the steps of 1, selecting and preparing a seedling raising land, to be specific, preparing the land, applying fertilizer, and ridging ;2, treating seeds, to be specific, grading the seeds in size, and subjecting the seeds to wet sand low-temperature burying or warm water soaking sprouting; 3, selecting a sowing season; 4, determining sowing density; 5, selecting a sowing mode, and carrying out hill sowing, and mulching; 6, managing a field, to be specific, weeding, topdressing, and irrigating; 7, controlling disease and pest damage; 8, outplanting. By breeding plantlets of Xanthoceras sorbifolia through the method, seedling raising cost is lowered, and the yield per unit area is increased. Both height and basal diameter increase of plantlets are higher than those of a control, and the qualification rate of plantlets is significantly increased. The bred robust seedlings of Xanthoceras sorbifolia are widely applicable to afforestation in various areas, and economic, social and ecological benefits are greatly improved.
Description
technical field [0001] The invention relates to a method for breeding forestry seedlings, in particular to a method for raising seedlings of sorbifolium sorbifolium. Background technique [0002] Xanthoceras sorbifolia Bge., Sapinaceae, Xanthoceras genus, is a unique woody oil tree species and the preferred ecological and economic tree species in northern China. It is widely distributed in northern my country, about 33 north latitude 。 north to latitude 46 。 Barren mountains, valleys, hills, and sandy land are distributed in the south, and there are sporadic plantings around the temples. [0003] Xantho sorbifolium is full of treasures and has many functions such as barren hills greening, water and soil conservation, windbreak and sand fixation, medicinal, health care and ornamental. It takes 3 years for seedlings and 2 years for tiller seedlings to bear fruit, enters the full fruit period in 5 to 7 years, and has a life span of more than 100 years. [0004] Chifeng City,...
