How to reduce cold injury in legume crops

摘要

PURPOSE:To reduce damage by low-temperature hindrance and stably obtain a leguminous crop in high yield by feeding an amino acid fermentation liquid to the crop during a term from budding to blooming. CONSTITUTION:Total concentration of amino acid of an amino acid fermented liquid (e.g. obtained by subjecting an amino acid fermentation raw material containing glucose, vitamin and yeast extract to amino fermentation is controlled to 5-100ppm and the amino acid fermented liquid is fed to a leguminous crop =3 times at the intervals of one or more weeks in the amount of 10-40ml per stock during a term from budding of leguminous crop to blooming.
