6、A team of Chinese biologists solved a long-standing puzzle in crop growth.
7、Developing strategy of grain crop production in Loess Plateau Region of China.;
8、Scaling effect on spatial variability of soil organic matter in crop land
9、Wheat rust once spurred the Green Revolution, the huge increase in crop yields that started in the 1940s.
10、In this way, farmers have enough moisture to produce a grain crop in each strip every other year.
11、It is easy to demonstrate that the addition of inorganic fertilizers makes rapid and significant improvements in crop yields.
12、Our objective was to explore why Sesamum indicum yield declined severely when planted after Rehmannia glutinosa in crop rotation.
13、Of course, wealthy countries are affected: long-term drought in Australia has caused certain crop yields to plummet.
14、Salt tolerance, like other important agronomic traits in crop plants, is complex trait controlled by quantitative trait loci (QTL).
15、Agriculture is one of the world's largest economic sectors, with billions of dollars invested in crop and livestock production.
16、Promoting smallholder participation in crop production, including for biofuel, requires investment in infrastructure, research, rural finance, market information and institutions and legal systems.
17、The method of pollen tube pathway was formally established in 1983. Since then, it has been widely used in crop genetic improvement.
18、Three typhoons churn through Asia in a week, a heatwave bakes the northern hemisphere and a drought slashes grain crop estimates in Australia.
19、The research shows that nicer environments enriched the abundances of natural enemies in crop fields, which markedly controlling some major insect pests.
20、Incipient shearing of main crop ore shows the development of hairline mylonitized shear zones that rapidly increase up to 2mm in width.
21、Farmers can lose rather than gain if incomes fluctuate because of variations in crop yields and outputs-stable prices can then destabilize incomes.
22、Fuzhou, Yunxiao, Shouning and Longyan were taken for examples to study the productive potentiality of the major grain crop (paddy rice) in Fujian province.
23、Soil desiccation characteristics of alfalfa grasslands and soil water restoration effects in alfalfa-grain crop rotations on the semi-arid areas of the Loess Plateau
24、Flax is a main crop in the adjustment of agricultural planting structure in reclamation areas,2/3 of the total flax area in Heilongjiang Province was concen trated in these areas.
25、The more photosynthates distributed in stems and sheathes at maturity of main crop, especially in internodes below the 2nd from the top, the higher yield of palingenesis rice would get.
26、Previous studies have linked increased acidity in oceans to damage to ocean food webs, while increased acidity in soils has the potential to affect their ability to sustain crop growth.
27、Paddy-upland rotation is a main crop cultivation systems and has an important position in ensuring crops stable yield, maintaining high yield and improving planting economic benefit in China.
28、Article 14 Land collectively owned by peasant shall be contracted out to members of the collective economic organizations for use in crop farming, forestry, animal husbandry and fisheries production under a term of 30 years.
29、Summer is the key season for the growth of seedlings in crop fields. If it does not rain for half a month, the seedlings will be dried to death.
30、Flooding disaster happened often in last ten years, the lost was tremendous and the price of grain crop was reduced, so the benefits from traditional agricultural production was very low.
