Strawberry (FragariaananssaDuch.) belongs to perennial evergreen herbaceous plants of the Rosaceae (Rosaceae) strawberry genus (Fragaria), has high nutritional and medicinal values, is a good name of 'cheap health products', and has a unique sweet taste of strawberry, which is the first place in the production of small berries. Therefore, most countries in the world have cultivated plants. China is the largest strawberry producing country in the world, the strawberry cultivation area and the normal annual yield are at the top of the world, and the strawberry cultivation area and the normal annual yield are one of the main domestic fruits and have huge market potential and economic benefit prospect.
The quality of the seedlings determines the growth condition and the later yield of the strawberries. At present, the strawberry seedling culture in China is mainly carried out in an open field seedling culture mode. Strawberry is grown seedlings in same plot for many years and can produce the plant short and small, the pest and disease damage takes place heavily scheduling problem, causes the strawberry to breed the seedling in small quantity, and the quality is poor, and the arable land area that china's arable land area is few, can be used for the strawberry to grow seedlings is more limited, consequently, how to increase the area of growing seedlings, cultivates high-quality seedling, improves economic benefits, is the main problems who awaits the solution in the strawberry production of growing seedlings.
The poplar belongs to deciduous trees of the family salicaceae, is loving light and water, has the characteristics of fast growth, strong disease resistance and the like, is planted in a large area in northern areas of China, mainly has prominent effects on industrial materials, ecological protection, agriculture and forestry protection and the like, and effectively relieves the current situations of forest resource shortage and wood shortage in China.
The seedling culture under the forest is slow in development, small in scale, less in distribution and low in technical level. The whole trend is that the development of forest regions lags behind garden planting, forest grain intercropping and forest medicine intercropping. The dependence of crop seedling on cultivated land is high, and the development of seedling under forest, especially the development of the north, is almost blank.
