为加速红富士苹果的繁殖,使嫁接苗能当年出圃,经试验,总结出了红富士苹果的“六早”育苗配套技术。此法成苗快,效益高,适宜推广。育苗的关键要做到“六早”,即早整地、早沙藏、早播种、早摘心、早嫁接、早肥水管理。 一、早整地。在土壤上冻前完成,每亩施腐熟的有机肥5000公斤,深翻30—40厘米,搂平作成长10米、宽1米南北走向的畦,而后在畦内浇透水。 二、早沙藏。沙藏以2月中旬为宜。将一份海棠种子与3份干净的湿沙混合均匀,沙子的湿度要
In order to accelerate the reproduction of Red Fuji apple, the grafted seedlings can be nursed out of the same year. After the test, the “six early” seedling supporting techniques of Red Fuji apples are summarized. This method into a seedling fast, high efficiency, suitable for promotion. The key to nursery to do “six early”, that is, early neat, early sand possession, early sowing, early topping, early grafting, early fertilizer and water management. First, early preparation. In the soil before the completion of the freeze, maturity of organic fertilizer per acre 5000 kg, deep flip 30-40 cm, louboutin pas cher, Louping for growth 10 meters wide and 1 meter north-south strike, and then drowned in water. Second, early sand possession. Sand reservoir in mid-February is appropriate. Mix a piece of crabapple seed with 3 parts of clean, wet sand to keep the moisture in the sand
