After 6 h saccharification at 30 ℃, compared with mash by uncooked wheat saccharification, the produced mash by cooked wheat starter saccharification, its liquefying power, saccharifying power and protein resolving power was better.

Comprehensive evaluation of tillage and straw returning on soil fertility in a wheat-rice double cropping system;

Effects of tillage and straw returning on soil fertility and grain yield in a wheat-rice double cropping system;

An experiment of 4 treatments (no-tillage+straw mulching,NTS;no-tillage+high stubble remaining,NTH;conventional tillage+straw incorporation,CTS and conventional tillage+ no straw returning,CT) was designed to investigate the effect of tillage and straw returning on soil fertility in a wheat-rice double cropping system for three consecutive years.

Cotton-wheat double cropping system is a main planting system in cotton cropping zones in China, but less research has been done in soil nutrient competition while more in light competition of up ground part of composite population in the symbiotic period of wheat-cotton.

In Huang huai cotton strict,for 2 kind of planting patterns of cotton wheat double cropping that were 3∶2 model and 3∶1 model,shading degrees resulting from the planting patterns in cotton wheat double cropping symbiotic period affected C metabolism and N metabolism,soluble protein content,POD activity and MDA accumulation of cotton seedling leaf.
