Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a small-sized vegetable seedling semi-automatic transplanter suitable for hilly and mountainous areas. Background Art

[0002] my country has a vast territory, with significant differences in climate and landforms, and a wide variety of crops. Different crops or the same crops are planted in different regions in different ways, and the planting patterns are diverse. Seedling transplanting is a planting pattern that transplants crop seedlings cultivated in trays in greenhouse substrates to fields. It has the comprehensive benefits of climate compensation and advancing the growth and development period of crops. It is an effective way to increase the multiple cropping index or resist low temperature and cold damage during the seedling stage, and achieve high yields and increased production. Mechanized transplanting can not only greatly reduce labor intensity, reduce labor costs, and improve production efficiency, but also the row spacing, plant spacing, and depth of the planted seedlings are consistent, which is conducive to subsequent mechanized field operations such as fertilization, weeding, spraying pesticides, and robot picking. It is an important link in realizing the full mechanization of crop production and standardized management. However, most of the current mechanized transplanters are agricultural automation machinery used in plain areas, suitable for flat and wide fields, but not suitable for hilly and mountainous areas with small fields and low flatness. Hilly and mountainous areas still use traditional manual transplanting methods, which are time-consuming and laborious.

[0003] Therefore, those skilled in the art are committed to developing a small-sized semi-automatic seedling transplanter that can improve planting efficiency and is suitable for hilly and mountainous areas. Utility Model Content
