我们在昆士兰达林顿的黑土地上进行了一系列有关小麦播量与野燕麦密度的田间试验.即用五种不同播量试验了五种不同的野燕麦密度.滋生野燕麦的地块如要获得较好的小麦产量,就得加大播量,而不能和无野燕麦的地块那样,采用那种最低的播量.播量加大到小麦群体密度超过150株/m~2时,成熟期野燕麦干重减少,而小麦干重增加.加大播量还可以降低野燕麦的产籽量,尤其在野燕麦群体密度低的情况下,更是如此. We conducted a series of field trials on wheat sowing and wild oat densities on the black soil in Darlington, Queensland, that tested five different wild oat densities at five different seeding rates. To obtain better wheat yield, you have to increase the amount of sowing, but not as non-wild oat plots that use the lowest sowing sowing increased to wheat population density of more than 150 plants / m ~ 2, The dry weight of wild oats decreased during maturity, while the dry weight of wheat increased.It could also reduce the seed yield of wild oats by increasing seeding rate, especially when the density of wild oats was low.
