小麦的播种深度是影响小麦苗壮和苗全的关键因素之一播种太深,延长了小麦的出苗期.消耗了大量种子营养,小麦出苗后生长瘦弱,甚至形成土里弯曲苗,造成缺苗断垄,然而播种太浅了.在土壤墒情不足和气候干旱的情况下,又容易造成种子落干.也同样影响小麦的苗全苗壮连续两年的试验结果表明.小麦播深1厘米、2厘米、3厘米的分别比5厘米的增产8.7%,9.7%和
Sowing depth of wheat is one of the key factors that affect wheat seedling growth and seedling growth, too much sowing, prolonging the emergence of wheat, consuming a lot of seed nutrition, thin growth after emergence of wheat, even the formation of bent seedlings in soil, resulting in lack of seedlings Broken ridge, however, sowing is too shallow in the soil moisture conditions and climate arid circumstances, but also easily lead to the seeds fall dry also affect the whole wheat seedlings splenome success for two years the test results show that the wheat sowing 1 cm, 2 cm, 3 cm, respectively, than the increase of 5 cm 8.7%, 9.7% and
