A new design of the divided no-till wheat planter has been accomplished by China agricultural University aimed to solve the extremely important problem of the double cropping area in North China, where the planter can easily be walled up by standing maize stubble when sowing the winter wheat.

2BMD-12 Row-controlled No-till Wheat Drill has been developed to plant wheat between rows of standing maize residue under double cropping condition.

A new-concept of no-till wheat planter, named 2BMD-12 no-till row-follow wheat planter, had been developed by China Agricultural University to solve an extremely important problem which is zero tillage planting of wheat in narrow row spacing (150-200mm) between rows of very high-levels full length, standing maize stubble in one pass in the double cropping situation of North China.

Conservation tillage for corn-wheat two crops a year region;

Conservation tillage has been used and spreaded in regions of two crops a year in recent years.

The conventional tillage pattern of two crops a year in North China Plain has played a very important role.

A better anti-blocking capability of no-tillage planter in double cropping area has become one key factor of production efficiency and seeding quality.

Study on effect of double-cropping system on moisture of dry farmland in the southeast Loess Plateau——A case study of Yangling;

In order to increase multiple cropping index and achieve increase of yield and income for farmers,four crops a year demonstrations of efficient planting test were carried out in Xinzhou town of Zunyi county from 2004 to 2008 involving seedless watermelon-premature and heat resistant cabbage-normal heat resistant cabbage-potherb mustard.
