Production and application practices have proved that virus-free strawberries are not only strong and have uniform plants, but also significantly increase yield and quality. Virus-free seedlings had a high growth rate of 17.7%-46.2% compared with virus-infected seedlings, leaf area ranged from 2.6%-17.2%, petiole length increased by 14.5%-41.9%, stolon number was more than 26.7%-89.5%, and harvest volume increased by 7.8%-45.1 %, fruit number increased 8.7% -18.6%, single fruit weight increased 0.67% -24.1%, soluble solid content increased 3.8% -8.3%. Virus-free seedling growth characteristics and common seedlings have inconsistencies, so also in cultivation Should be adjusted accordingly, in order to play the role of no virus seedlings to increase production and improve quality.
(1) Virus-free seedlings have strong nutrient growth and strong fertility. During flowering and nursery, they should avoid applying topdressing before flower bud differentiation to avoid delayed flower bud differentiation. The use of cutting off roots, removing old leaves and other measures to adjust the ratio of carbon to nitrogen in the body can make flower bud differentiation earlier.
(2) The non-toxic Miaotian is thicker and taller. Under the condition of a large amount of fertilizer, the endurance to the stronger concentration fertilizer is stronger than that of the poisonous seedling. However, too much fertilization should be avoided in the place of production so as to avoid excessive growth of the plants and affect the results. Compared with virus-inoculated seedlings, virus-free seedlings should be sparsely planted.
(3) There was a delay in the flowering period of virus-free seedlings, and the harvest period was also delayed. However, the early yield and total yield were still higher than the control. As the number of fruits in each inflorescence increases, the average yield of single fruit decreases, so moderate sparse fruiting should be considered to promote fruit enlargement. When the growth is too strong, gray mold and leaf blight are easy to occur. The old diseased leaves should be removed as soon as possible to prevent and treat diseases and insect pests in time. In the protected cultivation, ventilation in the shed must be taken care of.
(4) The rate of reinfection in the production process of virus-free seedlings may differ depending on the origin and cultivation management method. Small-scale production and frequent control of locusts are still virus-free after 2 years of cultivation, and mild infection only in the third year. Reproductive infections often occur within a short period of time. In general, new virus-free mother-tree breeding seedlings need to be used every 2-3 years. The original production seedlings should not be reused.
