The Effects of Fertilizer Application Operation on Physiology and Yield of Wheat
Bibliographic record
Abstract
The test based on high-yield characteristics of wheat cultivation technology,taking Guizi-4 as the tested material,designed different fertilizer application disposing,analysised and compared the effect of fertili- zation on physiological characteristics and yield of wheat,at the premise of N,P,K on consistent ratio in the whole growth period.The result showed that application in a range of 0 -270 kg/hm2 significantly increased dry matter accumulation of wheat,nitrogen accumulation,chlorophyll content,root vigor,leaf nitrate reductase activity and yield.Under applying Nitrogen Fertilizer in the same proportion as base and top-dress fertilizer, and increasing the nitrogen amount from 225 kg/hm~2 to 270 kg/hm~2,the dry matter accumulation and chloro- phyU content will increase,roots vigor and leaf nitrate reductase activity will strengthen,but the nitrogen accu- mulation of a plant and the yield is not obviously different in the same treatment.In this experimental condi- tion,applying 225 kg/hm~2 nitrogen in the jointing stage is the major way to coordinate nutrient supply and time allocation,to regulate and control the contradiction between the yield and physiological regulation of wheat.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
