农艺农机融合的设施番茄栽培参数优化研究

为了提高设施番茄栽培关键环节机械化水平,从农艺农机融合角度出发,在保证番茄产量和品质的基础上,亟需研究提出宜机械化操作的农艺标准.本试验以设施番茄为研究对象,以现有栽培密度和栽培畦规格为对照,通过春、秋两茬栽培试验,探究了设施番茄宜机化栽培的栽培畦参数及适宜密度.结果表明:在每667 m2栽培株数不变的条件下,改1.4...

Study on Parameter Optimization of Protected Tomato Cultivation Integrating Agronomy with Agricultural Mechanization

In order to improve the mechanization level in the key link of protected tomato cultivation,from the angle of integrating agronomy with mechanization,and on the basis of ensuring tomato yield and quality,it is urgently needed to study and put forward an agronomic standard easily operated bymechanization.Taking tomato with larger cultivated area in greenhouse as research object,the existing cultivating density and planting bed size as the contrast,this experiment carried out croping in spring and autumn,and explored suitable planting bed parameter and proper planting density for protected tomato cultivation.Results indicated that under the condition of not changing the constant number of cultivated plants per 667 m²,changing 1.4 m double row to 1.6 m double row or 1.6 m single line,and changing the wide strip narrow gap cultivation field to narrow strip wide trench planting beds,shrinking the narrow line space from 50 cm to 30 cm,increasing the wide line spacing from 90 cm to 130 cm could significantly improve the ventilation and light transmission characteristics of the wide rows,yet without obvious impact on tomato nutritional growth,yield and quality,although the light intensity in the lower part of the narrow row was decreased to certain extent comparing with that of the contrast.Therefore,from the perspective of integrating agronomy with agricultural mechanization and simplifying management procedure in later cultivation period,it is suggested to adopt special methods including cultivation by narrowing piece of land and widening furrow,fix planting on 1.6 m double row or single row,1900-2500 plants per 667 m².
