从附近乳牛场和一般农场运来的厩肥继续广泛使用以生产烤烟.应用率一般每英亩5-8吨,大部份厩肥都在耕烟地以前或以后不久施入. 厩肥的涨价和1975年烟草遇到的成熟问题也许是应严肃地考虑厩肥是不是真正需要的时间了. 片面地责怪厩肥作为造成去年烟草成熟不好的原因是错误的.其它因素,特别是气候,也许有更大影响,然而,厩肥无疑地加重了一个总要发生的问题. 试图答复“需要厩肥吗?”这问题,我们将首先看,厩肥的养份.一吨保存得好的牛粪约含10磅氮,5磅磷酸盐和10磅钾,约1/2的氮和2/3的钾含于液体部份而几乎全部磷酸盐都含于厩肥的固体部份.
Manure produced from nearby dairy farms and general farms continues to be widely used to produce flue-cured tobacco, generally 5-8 tons per acre, with most of the manure being applied before or shortly after cultivation. Prices of manure increased in 1975 Mature problems encountered in tobacco may be seriously considered when it is not really time to barnyard manure.Propogenically blame the manure as a cause of poor tobacco maturity last year is wrong.Other factors, especially the climate, there may be greater However, there is no doubt that the use of manure aggravates an issue that always occurs. In an attempt to answer the question “Do you need a manure?” We will first look at the manure stock. A ton of well-preserved cow dung contains about 10 pounds of nitrogen , 5 pounds of phosphate and 10 pounds of potassium, about 1/2 of nitrogen and 2/3 of potassium are contained in the liquid part and almost all of the phosphate is contained in the solid part of the manure.
