Seedling foliar fertilization after callus formation cuttings often foliar fertilizer, generally one week to recover once the initial spray 0. l% ~ 0. 3 "of urea, the latter with 0.1% to 0.3" of urea and potassium dihydrogen phosphate mix spray, which is extremely beneficial to rooting and growth; foliar fertilizer should be selected after spraying be stopped in the evening; at the same time spraying fertilizer, which can rely on spraying, zinc and other trace elements and 2, China seedlings network, 4-0, growth hormone indole butyric acid, the active ingredient in order to increase rooting, mention Gao cutting survival rate. Row crop cultivators seedlings after draining topsoil to be slightly dry (with non-stick shovel appropriate), to timely cultivator. The purpose is to accelerate the cultivators of soil moisture evaporation, increase soil permeability, help restore vigor and prevent steep root. 4. Adding fertilizer available crop after flooding, soil nutrients huge loss, coupled with weak root absorption capacity, timely fertilizer plant growth beneficial for recovery. Before the plant growth recovery to Yemianpenfei based, you can choose some foliar common market based on the actual situation. After recovery plant growth, then the root fertilization, seedlings Buying, Adding P and K and trace elements, enhance plant resilience. 5, pest by floods, seedbed or basin, high temperature, humidity, Fengjie seedlings, coupled with weak growth of the plants, nursery stock price, reducing resistance, trees easily infected ulcer disease, rot, black spot and other diseases Therefore, the water is discharged in a timely manner after trees general fungicide spray again. To prompt investigation and prevention, to control the spread. For local prevention poplar canker, rot skin disease can be used 100 times or destroy bacteria will clear spiritual rot, a serious disease can be 50 times the liquid brushing trunk; choice of black spot disease prevention Poplar 800 25% chlorothalonil times, or 70% thiophanate-methyl 1500 times, or 50% carbendazim 1000 times spray the whole tree can be added when the mixed liquid urea and 0.3% potassium dihydrogen phosphate foliar fertilizer at the same time. Time for chemical control spray every seven days, and even spray three times. You can also choose efficient, low toxicity of pesticides to control counterparts; in case of rainy weather after application, have up spraying again, disease prevention and control in general medicine 2 to 3 times.
