Weed control in grassland newly established in different seeding times with different pioneer species;

Method Zhengdan958 were studied and it was designed to be eight different seeding times and four different sampling times.

The test is designed to observe its seeding time,fixed date of planting and factors that affect its growth and flowering quality.

Effects of sowing time on grouth and dry matter content of super high-yield ratoon rice

The best sowing time of Haloxylon ammodendron in the east of Helan Mountain in Ningxia autonomy is studied.

The result indicated that Cicer arietinum can be cultivated successfully under the non-irrigation condition of farming and livestock areas in North Xinjiang,and also indicated that the best sowing time is the first ten days of April.

Effect of climate change on maize sowing date in the east of Gansu;

Studies on full heading time and optimized sowing dates of hybrid rice Liangyoupeijiu;

Influence of sowing date on seed yield and quality in dwarf bean (Phaseolus vulgaris var. humilis Alef.);

The experimental research illustrated that the proper seeding date of Glyrrhiza uralensis Fisch is much longer than we expected: setting seeds during late April to early August can help it to pass the winter safely.

Seeding date affected sig.

In order to popularize the new double low cultivar of rapeseed with high yield, the relationship between seeding dates and development characters and seed yield formation of Xiangnongyou571 was studied.
