摘要

摘要李建军,李建军,李建军,等。2009。不丹萨尔邦地区下带的种植格局和种植强度。农业学报7:1-6。关于种植和耕地利用的信息对于提高作物产量和确定生产差距至关重要,包括规划和投资。在许多国家,通过采用多种方法提高种植强度可以提高作物产量,而不是给农田扩张带来压力。就不丹而言,缺乏关于不丹种植及其强度的信息。本研究采用多阶段随机抽样技术,对沙邦县农户的种植模式和种植强度进行了调查。该地区记录了不同形式的复种做法,但大多是小规模和间歇性的。湿地以水稻为主,旱地以玉米或蔬菜为主。平均种植强度为112%,旱地和湿地的种植强度分别为97%和126%。农户特征中土地持有规模与种植强度呈显著负相关。该地区最严重的农业问题是缺乏灌溉用水和野生动物捕食作物。该研究建议在国家一级进行类似的研究,并制定适当的集约化农业土地利用战略,以尽量减少未来对农田扩张的压力。同样,农业规划和投资也需要对作物多样性、作物生产资源、种植强度差距和作物制图进行评估。

Cropping pattern and intensity in the lower belt of Sarpang District, Bhutan
Abstract. Tashi T, Tobgay T, Wangmo T, Kinley R, Gyeltshen S. 2023. Cropping pattern and intensity in the lower belt of Sarpang District, Bhutan. Asian J Agric 7: 1-6. Information on cropping and farming land use is vital for increasing crop production and identifying production gaps, including planning and investment. Increasing cropping intensity through adopting multiple approaches increases crop production rather than pressure on cropland expansion in many countries. In the case of Bhutan, there is a shortage of information on cropping and its intensity in Bhutan. This study presents the status of cropping patterns and cropping intensity at the household level in the Sarpang District using a multistage random sampling technique. Different forms of multiple cropping practices were recorded in the district but were mostly practiced on a small scale and were intermittent. The rice-based cropping pattern was popular in wetlands, while the maize or vegetable-based cropping pattern predominated in dryland. With an average cropping intensity of 112%, the district had a cropping intensity of 97% and 126% for dryland and wetland, respectively. The landholding size revealed a significant inverse relationship with cropping intensity among farmer characteristics. The district's most serious farming problems were a lack of irrigation water and wildlife crop predation. The study recommends a similar study at the national level and developing appropriate intensification of agricultural land use strategy to minimize pressure on cropland expansion in the future. Similarly, agricultural planning and investment merit assessment of crop diversity, crop production resources, cropping intensity gap, and crop mapping.
