Some farmers in the harvest of legumes, especially legumes such as beans, peas, cowpeas, beans, etc., are often accustomed to pulling up the stems by hand. This harvesting method is unscientific and invisible waste. Many organic nitrogen-fixing fertilizers are unfavorable to the high yield of post-crop crops.
The legume crops include some grain and oil crops such as soybeans, adzuki beans, mung beans, and legumes. They are nitrogen-fixing crops. Their nutrients are root nodules and can fix free nitrogen in the air, and provide this season's crops and crops. The nitrogen requirement of the crop. According to the determination, every 667 square meters of bean crops can fix 7-10 kg of nitrogen from the air, equivalent to 35-50 kg of ammonium sulfate. For example, rhizobia of 667 square meters of peas, a growing season can fix nitrogen 9.5 kilograms, equivalent to 47.5 kilograms of ammonium sulfate. If roots are removed at the time of harvest, root nodules that store organic nitrogen will be taken away. This is a pity. It is suggested that when harvesting leguminous crops, the farmers' friends should use a sickle to harvest them, not to root them, in order to lay a foundation for the high yield of the crops after the crops.
