种植方式对不同地区张杂谷10号抗倒伏特性及产量的影响

探讨种植方式对不同地区张杂谷10号抗倒伏性和产量的影响,为谷子抗倒伏和高产栽培提供理论依据。试验于2020年在山西省定襄县、太谷区和泽州县进行,以张杂谷10号为试验材料,设置覆膜穴播（MX）、膜侧条播（MT）、裸地穴播（LX）和裸地条播（LT）4种种植方式,分析种植方式对不同地区张杂谷10号茎秆第1和第2节间抗倒伏特性及产量的影响。结果表明,张杂谷10号的株高和重心高度表现为覆膜处理高于裸地处理。在定襄和太谷试验地,MX处理的第1、第2节间倒伏指数和节间长度最高,MT处理的第1、第2节间机械强度、节间充实度、木质素和纤维素含量显著高于其他处理;不同种植方式下,张杂谷10号产量表现出相同的趋势,即MX>MT>LX>LT,但MX与MT处理差异不显著。在泽州试验地,覆膜处理的倒伏指数显著高于裸地处理;LT处理的节间机械强度、节间干密度和节间充实度高于其他处理;裸地处理的木质素和纤维素含量显著高于覆膜处理;裸地处理的产量高于覆膜处理,且LX与LT处理之间差异不显著。综上所述,种植方式对不同地区张杂谷10号植株倒伏相关指标及产量形成有较大影响,在定襄县和太谷区适合张杂谷10号高产抗倒伏的种植方式是膜侧条播,在泽州县的最佳种植方式是裸地条播。

Effects of Planting Patterns on Lodging Resistance and Yield of Zhangza 10 in Different Ecological Areas

In order to provide the theoretical basis for guiding lodging resistance and high yield cultivation of Zhangza 10, we explored the effects of planting patterns on lodging resistance and yield of foxtail millet in different ecological areas. The experiment was conducted in Dingxiang county, Taigu district, and Zezhou county of Shanxi province in 2020. Zhangza 10 was used as the test material and four kinds of planting patterns were set up, the film-covered hole seeding (MX), membrane side seeding (MT), bare ground hole seeding (LX) and bare field sowing (LT). The effects of different planting patterns on lodging resistance and yield of the first and second internodes of foxtail millet stem in different ecological areas were analyzed. The results showed that the plant height and the gravity center height of Zhangza 10 were higher in the mulching treatment compared to the bare soil treatment. In Dingxiang and Taigu, the first and second internode lodging indexes and internode length of MX treatment were the highest and the mechanical strength, internode fullness, lignin and cellulose contents of the first and second internodes of MT treatment were significantly higher than other treatments. The yield of Zhangza10 under different treatments showed the same trend of MX > MT > LX > LT, but there was no significant difference between MX and MT treatments. In Zezhou, the lodging index of the mulching treatment was significantly higher than that of the bare ground treatment. The mechanical strength, clam dry density and clam filling degree of the LT treatment were higher than that of other treatments; the contents of lignin and cellulose of the bare soil treatment was significantly higher than that of the film treatment. The yield of the bare ground treatment was higher than that of the mulching treatment, but there was no significant difference between LX and LT treatments. In summary, different planting patterns had a greater impact on the lodging related indicators and yield formation of Zhangza 10 in different ecological areas. In Dingxiang and Taigu, the suitable high-yield and lodging-resistant planting pattern of millet was the membrane side seeding and bare field sowing was the best planting pattern in Zezhou.
