Culture Technique on High yield of Highland Barley in Gonghe Basin;

The technique system of excellent and high yield cultivation is put forward to instruct production.

And its cultivation techniques for high yield like orchard construction, soil and irrigation management, management in flowering phase, insect and disease control, harvest, etc, are summarized.

Research Advance in the High-yielding Cultivation Technique of Polygonum multiflorum Thunb;

Basd on relative research results the cultivation technique system and technical standard of high-yield and high-value of transplanted cotton after harvested rape was developed.

Systematic measures are put forward for the high-yield cultivation,including planting technique, management of young and mature plantation, and pest control.

The growth and fruiting features were invested consistently for five years in young precocious walnut, and then the indexes of tree structure for its highyield were pointed out.

Through the research on the ecological adaptation,biological characteristics and the multi purpose planting of Kaite apricot,many technical problems have been solved and its highyield planting in hilly region of southe Henan province is guaranteed technically.

The high and stable yield ability of 7 varities of dry-land wheat in the regional test in north part of China was studied by using the methods of high-stable coefficient, parameter of adaptability and coefficient of variation.
