海丰稻作区不同种植方式下南粳9108的综合评价

Comprehensive Evaluation of Different Ways of Rice Cultivation on Haifeng Rice Planting Area of Nanjing 9108

在海丰农场种植条件下,对水稻品种南粳9108 4种不同种植方式技术和经济效益开展综合评价与分析。结果表明,4种种植方式下南粳9108的产量均达9 000 kg/hm2以上,人工插秧产量最高,其余依次为:机械旱直播、机穴播、机条播;投入成本以人工插秧最高,达13 023.0元/hm2;机穴播和机条播其次;而机械旱直播最低,仅为10 338.0元/hm2。特别在人工投入上,人工插秧最高,机条播和机穴播较低;机械旱直播、机穴播和机条播经济效益较高,经济效益分别为17 763万、17 469和17 301元/hm2;人工插秧最低,仅为15 834元/hm2;从产出投入比来看,规律与经济效益高低相同。因此,无论从提高经济效益考虑还是从减少用工考虑,目前机穴播、机条播和机械旱直播等轻简栽培方式作为海丰水稻主要种植方式是合理的。

Under the condition of Haifeng rice planting area,the comprehensive evaluation and analysis was carried out on technical and economic benefits of Nanjing 9108 four different cultivation ways. The results showed that four types of rice cultivation production levels are more than 9 000 kg / hm^2. For artificial planting the highest yield,and the rest in the order： dry direct seeding,dibbling,direct seeding rice; The highest cost for artificial planting,868. 2 yuan,the rest in the order： dibbling,direct seeding rice,dry direct seeding rice. Especially on the manual input,artificial planting and machine planting are higher,dibbling and direct seeding rice are lower. Dry direct seeding rice,dibbling and direct seeding rice have the highest economic benefit（17 763,17 469,17 301 yuan / hm^2,respectively. Artificial planting has the lowest economic benefit,15 834 yuan / hm^2. Therefore,no matter from improve economic efficiency and reduce labor into consideration,the dibbling,direct seeding rice and dry direct seeding rice as Haifeng main rice planting form is reasonable.
