科学耕作

The agriculture soils of Baimahu ,Lushan and Zoujiao are the typical cases in the suburbs of Changde. Rice soil and vegetable plot are the two typical agriculture soils, we collected 6 samples according to the scientific method in these three areas. After air dry, contuse, screen and make soil samples, we tested their 9 indexs of PH, organic-substance, total phosphorus, quick-acting phosphorus. Then analysed the fertility condition of these areas. Then apply feasible suggestion of fertilizer after putting forward science and suiting measures to local conditions etc, by Compare with the documents and materials. Absorb to Model TAS-986 atom spectrophotometer examine with flame law (air - acetylene ) terms of potassium make deep discussion especially.

白马湖，芦山乡和陬郊的耕作土壤是常德市郊区耕作土壤的典型代表，在这三个地区分别就水稻土和菜地这两个基本的土地耕作类型按科学的方法共采集了6个样品，经过风干，研碎，过筛制成土样后，测定了它们的PH，交换性酸，有机质，全磷，速效磷等9指标，从而对该地区耕作土壤肥力状况进行分析，对比文献资料，总结分析结果，针对不同地区不同的土壤状况，提出了科学施肥，因地制宜等可行性建议，尤其是对TAS—986型原子吸收分光光度计用火焰法测钾的条件作了深入的探讨。

It is significant to investigate more scientific and reasonable wheat no-tillage planter evaluation methods for generalization and application of conservation tillage.

在发表于8月1日出版的《环境科学与技术》的一篇论文中，英国洛桑研究所的赵方杰及其同事比较了淹水种植的水稻与旱作种植的水稻之间的砷水平，淹水种植水稻是南方国家最传统的耕作方法，而旱作种植水稻则指的是不把水稻根部浸于水中的做法。

To change the grain increase method we must first carry out reform, optimize the industrial structure and farming system, stress scientific management, enhance the level of intensive farming in grain production and raise the utilization rate of agricultural resources.

转变粮食增长方式，要从改革、优化产业结构和耕作制度，加强科学管理，提高粮食生产集约化程度和农业资源有效利用率等多方面入手，但最主要的是依靠科技进步，加快科教兴粮步伐，走高产、优质、高效、低耗的路子。

While various operators are carrying out the adjustment of agricultural structure and development of competitive characteristic industry, their cultivation of crops, poultry and cattle rearing, aquiculture and facilities for agricultural scientific experiment shall be taken as the purpose for agriculture with the prerequisite of not violating relevant laws and regulations and policies and not destroying the condition for land cultivation.

各类规模经营主体在进行农业结构调整、发展优势特色产业时，在不违背有关法律法规和政策规定、不破坏土地耕作条件的前提下，其农作物种植、畜禽饲养、水产养殖、农业科学实验设施等视为农业用途。

Now, scientific farming has been applied in all aspects of farming, the old methods have been eliminated, orchard pruning of young people, most of the village hired agronomists, spring improvements, may be next year after a high yield.

现在，科学种田已经适用在耕作的方方面面，老的方法已经被淘汰，果园里修剪的年轻人，大多是村里请来的农艺师，今春的改良，可能就是明后年的丰产。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
