Abstract

The invention relates to the field of agricultural fertilizers, in particular to a foliar fertilizer for promoting potato yield increase. The foliar fertilizer comprises the following components by weight: 100mL of water, 3.0-7.0g of polyglutamic acid, 3.2-6.0g of an amino acid synergistic component, 0.1-2.0g of ferric chloride, 0.2-3.0g of manganese sulfate, 0.2-2.0g of copper sulfate, 0.4-2.5g of boric acid, 2.0-10.0g of dipotassium hydrogen phosphate, 0.5-2.0g of potassium chloride and 0.2-5.0g of zinc sulfate. The foliar fertilizer acts on the surfaces of potato leaves and functions through the absorption of the leaves; because the surfaces of potato leaves have many tiny pores, the pores facilitate the gas exchange of the potatoes, and the pores are also convenient passages for the foliar fertilizer to enter the potato leaves; and the foliar fertilizer can increase the potato yield by 38.9% per mu, has the advantages of being low in cost, good in absorption and obvious in yield increase effect, and can be widely applied to potato production.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a foliar fertilizer for increasing potato production. Background technique [0002] Potatoes, also known as potatoes, have stem-like fruits, oblate or 15-80cm high, spherical, glabrous or sparsely pubescent. It is an annual herbaceous plant belonging to the family Solanaceae, and its tubers are edible. Together with wheat, rice, corn, and sorghum, it has become the world's top five crops. Potato has wide adaptability, short growth period, comprehensive nutrition and long industrial chain, great potential for increasing production and broad prospects for industrial development. It has become an important pillar industry in my country. [0003] In the growing process of potatoes, rapid stem and leaf growth is required at the seedling stage and the recovery period after encountering drought or frost, and traditional fertilization cannot meet the demand quickly and effectivel...
