一、产量指标:亩产300-500斤二、生产存在的主要问题我省丘陵旱地小麦生产存在的主要问题是一旱二薄.旱:在小麦生育期内(包括底墒)豫西、豫北降雨仅200毫米左右;豫西南也不过300毫米上下,且易发生播种、冬、春等季节性干旱,是旱地小麦增产的最大障碍.薄:一般土壤有机质在0.08%以下,有效氮在40PPM以下,速效钾在90-120PPM,速效磷多在5PPM以下,为严重缺磷,致使小麦生长不良,产量低而不稳.

I. Yield Index: 300-500 kg per mu 2. Main Problems in Production The main problem in the production of wheat in the hilly drylands of our province is arid and arid dry: during the growth period of wheat (including end moisture content), western Henan and northern Henan Rainfall is only about 200 mm; southwest of Henan but also 300 mm up and down, and prone to sowing, winter, spring and other seasonal drought, is the biggest obstacle to increase wheat yields in dryland. Thin: the general soil organic matter below 0.08%, effective nitrogen below 40PPM , Available potassium in 90-120PPM, available phosphorus more than 5PPM, a serious shortage of phosphorus, resulting in poor growth of wheat, low yield and instability.
