在苹果树上使用多效唑的简易方法多效唑（又称ｐｐ＿（３３３）对控制桃、李、杏、苹果、梨等树种的过旺生长，促进其提前结果、早期丰产效果十分显著。但现行的使用方法土施、喷施技术要求较高，浓度、剂量较难控制，使用时费工。为此，中国农科院果树研究所与绥中县沙河乡果树站联合研制试验了一种多效唑新剂型，经过一年试验，二年示范推广，效果令人满意。处理者花序座果率可达９０％以上，花朵座果率５０％以上，节间缩短３３．９５％，枝条增粗２８．２６％。用此药剂，省时、省力、节水省药，使用浓度、剂量容易控制。一斤药可处理４０－６０株树，每人每天可处理３００－５００株。药价１６元。具体方法如下：１药剂配制在室温下先将１３３．５公斤水倒入大桶中，再倒入渗透剂４０公斤（它由１００％的固体平平加与Ｔｗｅｔｈ－８０两种药剂混合而成），不断搅拌并加入６６．５公斤多效唑，待多效唑完全溶化为止。水、渗透剂、多效唑的比例为２：０．６：１。药剂成品后为乳白色悬浊液。２使用时间及方法先将药液摇匀，然后用刷子蘸取药液在树干距地面２５～３０ｃｍ处均匀涂抹一周，宽度因树势强弱而定，太旺树可适当宽一点。涂后１２小时不遇雨水冲刷即可。使用时间一般可从６月上中旬到９月
The simple method of using paclobutrazol in apple trees Paclobutrazol (also called pp_ (333) is very effective in controlling the over-growth of peach, plum, apricot, apple, pear and other tree species and promoting its early yield, Methods Soil and spraying techniques require higher concentration, dosage is more difficult to control, the use of labor time.Therefore, the Chinese Academy of Agricultural Sciences Institute of Fruit and Shahe Township, Suizhong County fruit tree station jointly developed and tested a new type of paclobutrazol , After a year of trial, two years of demonstration and promotion, the effect is satisfactory.Processors inflorescence fruit rate of more than 90%, fruit rate of more than 50% of flowers, internodes shortened 33.95%, branches thickening 28.26 %. With this medicine, save time, effort, water-saving medicine, the use of concentration, dosage easy to control. Pounds of medicine can handle 40-60 trees per person per day can handle 300-500. The method is as follows: 1 Pharmacy Preparation 133.5 kg of water into the vat at room temperature, and then poured into the penetrant 40 kg (which consists of 100% solids flat And Tweth-80 two agents mixed), stirring constantly and add 66.5 kg paclobutrazol until the paclobutrazol completely dissolved until water, penetrant, paclobutrazol ratio of 2: 0.6: 1 after the agent is milky white Suspension .2 time and method of first shake the liquid, and then dipped with a liquid brush in the trunk 25 ~ 30cm from the ground at a uniform application of a week, the width of the strength due to the tree may be too wide tree too wide A little rain after 12 hours of coating can be applied to the use of time generally from mid-June to September
