晚播麦早出苗是早发高产的先决条件。如何争取晚播麦早出苗?我们在公社科技站和县气象站的协助下,做了如下试验。 1.催苗与不催苗试验:11月28日把催苗种子和浸种不催苗种子分别播种,播后立即浇水。12月4日以前,天气晴,气温较高,5日～8日下大雨,10日以后连续低温。催苗处理的12月7日即出苗,比不催苗的提早了十二天。试验表明,11月20日以后播的麦子一定要先催芽,可争得晚播三麦早出苗。 2.浇水、不浇水与浇水盖垃圾的对比
Early sowing wheat early emergence is a prerequisite for early high yield. How to get late seedlings of wheat early emergence? We are in the commune science and technology station and the help of meteorological stations, the following test. 1. Vaccination and non-reminder vaccine test: On November 28 the seedlings and seed soaked seedlings were not seeding seed sowing immediately after sowing. Before December 4, the weather was fine and the temperature was high. It rained on the 5th and 8th, and continued to be low on the 10th. Vaccination treatment December 7 that is sprouting, do not urge the seedlings earlier than 12 days. Experiments show that after November 20 wheat sowing must first germination, can win late sowing three wheat early emergence. 2. Watering, watering and watering the lid contrast
