Single Season Rice Intensification Techniques
Rice intensification technology is a high yield of new technology, the core content is selected by taking a big spike tillering varieties, transplanting seedlings, one of this (or less of the) Sparse, light wet irrigation, organic manure and P and K, focusing on the application of balanced fertilization and panicle and other technical measures to strengthen the environment for the growth of individual rice plants to fully tap (or enhanced) production potential of individual rice plants. single cropping of rice cultivation can significantly strengthen the implementation of increasing production and efficiency. If the city in 2006 SRI technology demonstration Single Season approximately 33.3hm 2 , universal access to high-yield harvest. According to Liu Shouchang Town Village, Hang Town South eight villages, Jue village five farmers paid the real cutting production survey, SRI's Single Season 16 fields were 2.06hm 2 , the average yield to 9 928.5kg/hm 2 , compared with traditional cultivation techniques to increase grain yield in the same Single Season 1 125kg/hm 2 or so, yield increased to 13% of direct income 1 800 yuan / hm 2 or so. Liu Shi Town, Village, which Shouchang States Air China Town before and soil root Jue Tong Sun, Sun Lin, and other farmers in the production of water, more than 10.5t/hm 2 , played a good exemplary role. Planted in 2007 the city SRI Single Season 346hm 2 , universal access to high-yield harvest, according to 14 towns and villages 119 15.47hm 2 SRI's Single Season chattels survey, the average yield 9 168kg/hm 2 , than the adjacent conventional cultivation of single cropping of rice farmers increase 1 471.5 kg / hm 2 , yield 19.1%, average increase 2 648.7 yuan / hm 2 . <FONT Style= 2 , than the traditional half-length dry nursery seedling age (30d or so) transplanting,[link widoczny dla zalogowanych], field to save hybrid seeds 3.75kg/hm 2 or so, you can save 105 to 120 seed money / hm 2 . Short semi-dry nursery seedling age (12 ~ 18d) transplanted, the general field only seed 7.5kg/hm 2 , than the traditional half-length dry nursery seedling age (30d or so) can save the seed field 2.25kg / hm 2 , can save the seed money 75 / hm 2 or so. <FONT Style=only seedling 90m 2 / hm 2 , with the traditional semi-dry nursery length of seedling age (30d or so) than transplanting, to save seedling 900m 2 / hm 2 or more. Therefore, significant savings order seedling, planting, fertilization, irrigation and lift seedlings of employment, the general field seedlings and pulling seedlings can save labor 15d/hm 2 around, saving costs 600 yuan / hm 2 or more. Water seedlings with a short seedling age (12 ~ 18d) transplanting, seedling field only 300 ~ 450m 2 / hm 2 , and long seedling age (30d or so) semi-dry nursery phase than to save the seedling 450 ~ 600m 2 / hm 2 . Therefore, the field order to save seedling, planting, fertilization, irrigation and lift seedlings of employment 7.5d/hm 2 around, saving costs 300 yuan / hm 2 or more. <FONT Style=2 or so, a short semi-dry nursery seedling age and transplanting, each working day can also be planting 733.7m 2 around, and transplanting of seedling age long traditional semi-dry seedbed compared to (each Labor Day planting 466.9m 2 or so), can greatly improve the working efficiency, saving about half of the planting time. Field planting labor cost savings of at least 375 yuan / hm 2 or more. At the same time, you can also pick seeding and planting to reduce the labor intensity.
