However , long term issues of zero tillage need to be explored to determine whether future problems or benefits may arise for this technology 但還需要研究免耕的長(zhǎng)期影響,以確定這項(xiàng)技術(shù)將來是有利還是有害。
Data in table 8 and numerous field observations show that because the soil is less disturbed , zero tillage results in less weed populations than conventional tillage 表8的資料和一些大田觀察資料表明,因土壤較少被擾動(dòng),免耕比傳統(tǒng)耕作的農(nóng)田雜草群體更少。
When this was done with the proper equipment , results from six sites in 1986 - 87 showed an average wheat yield of 3677 kg / ha with zero tillage against 2598 kg / ha with conventional tillage ; higher wheat due to earlier planting of wheat by 24 days 1986 ~ 87年6個(gè)點(diǎn)的結(jié)果表明,使用合適的機(jī)具免耕,平均小麥產(chǎn)量3677公斤/公頃,傳統(tǒng)耕作只有2598公斤/公頃;高產(chǎn)來自早播小麥24天。
Although zero tillage technology presents a potentially dramatic breakthrough for planting wheat in rice - wheat system , there are two issues meriting attention : danger of increasing population of stemborers for the following rice crop and the application of fertilizer , particularly n fertilizers 雖然免耕技術(shù)為稻麥制中播種小麥提供了潛力巨大的技術(shù)突破,但有二個(gè)問題值得注意:后茬水稻螟蟲群體增多的危險(xiǎn)和施肥,尤其是施氮肥的問題。
