果树施肥不足。会使果树的生长、结果和果实品质受到严重影响。为了加强果园土壤的施肥管理,解决粮果争肥的矛盾和从战备观点出发,我们应当发展果园绿肥。现将“果园种植绿肥对改土肥田、壮树增产、提高果品质量试验”的部分结果小结如下: 一、试验设置试验从1974年开始在本所果园进行,土壤为麦黄土(平地棕黄土),苹果树品种为红星,树龄七年,密度7米×7米。试验分三个处理(见表1),每处理20株。
Fruit trees lack of fertilizer. Will result in the growth of fruit trees, the results and the quality of the fruit will be seriously affected. In order to strengthen fertilization management of orchard soil and solve the conflict between grain and fruit for fattening and starting from combat readiness, we should develop orchards green manures. Part of the results of the “green orchard fertilization of fertilizer on soil improvement, strong tree production, improve fruit quality test” are summarized as follows: First, the experimental set test Since 1974, the orchard, the soil is wheat loess (flat brown loess) , Apple tree breed Red Star, seven years old, density 7 m × 7 m. The test is divided into three treatments (see Table 1) with 20 plants per treatment.
