中文摘要:
      为探讨砂姜黑土农田适宜的耕作方式,提升砂姜黑土农田地力及作物产量,发挥地域资源优势,以百农207为试验材料,通过田间试验,研究了免耕、旋耕(15cm)和深耕(30cm)3种耕作方式对砂姜黑土农田土壤容重、土壤含水量、硝态氮含量及小麦籽粒产量的影响。结果表明,在小麦越冬期和成熟期,3种耕作方式0~10cm土层土壤容重差异不显著(P>0.05),但深耕处理显著降低了10~40cm土层土壤容重(P<0.05)。在小麦苗期,3种耕作方式对0~40cm土层土壤含水量影响规律不明显(P>0.05),但在小麦越冬期、拔节期、成熟期,深耕处理显著增加了0~40cm土层土壤含水量(P<0.05)。在小麦成熟期,0~40cm土层土壤硝态氮含量均为免耕>旋耕>深耕。与免耕处理相比,深耕处理通过增加小麦穗粒数和千粒重,使籽粒产量增加9.79%。综合研究区的土壤性质、作物生长、自然环境等因素,小麦季30cm深耕可以降低土壤容重,增加土壤含水量,提高小麦籽粒产量,可作为砂姜黑土农田适宜的耕作方式。
英文摘要:
      To select appropriate tillage method and improve soil fertility and grain yield and develop regional resource superiority in shajiang black soil, a field experiment was conducted to study the effects of 3 tillage methods [no tillage, rotary tillage (15 cm) and deep tillage (30 cm)] on soil bulk density, moisture, nitrate nitrogen and grain yield of winter wheat with‘Bainong207’as the material. The results showed that soil bulk density had no significant differences among the 3 tillage treatments in 0-10 cm soil layer (P >0.05), but deep tillage decreased soil bulk density in 10-40 cm soil layer significantly (P <0.05). The effect law of the 3 tillage treatments on 0-40 cm soil moisture was not obvious in wheat seedling period (P >0.05), but deep tillage significantly increased soil moisture of 0-40 cm soil layer in the wintering, jointing and maturity period (P < 0.05). In 0-40 cm soil layer, the order of soil nitrate nitrogen content was no tillage> rotary tillage> deep tillage at maturity stage. Compared with no tillage, deep tillage increased grain yield by 9.79% by increasing grain number and 1000-grain weight. In view of soil properties, crop growth and natural environment, the deep tillage (30 cm) was a better management practice for shajiang black soil to decrease soil bulk density, improve soil moisture and increase grain yield of winter wheat.
