Abstract
The invention relates to a rice leaf fertilizer rich in trace elements of boron, molybdenum, selenium, chromium and cobalt and application thereof; the rice leaf fertilizer, per 150 parts by weight, is prepared from, by weight, 3.0-3.5 parts of sodium selenite, 60-70 parts of disodium octaborate tetrahydrate, 7.8-9.0 parts of ammoniummolybdate, 15-16 parts of amino acid chelated cobalt, 14-16 parts of amino acid chelated chromium, 2.5-3.5 parts of aspirin, and the balance of sodium glutamate. Application includes: adding water to dilute the rice leaf fertilizer to 150-250 times, and spraying leaves at initial heading stage and full heading stage of rice respectively. The rice leaf fertilizer of the invention is simple to apply, the content of boron, molybdenum, selenium, chromium and cobalt in the rice can be correspondingly increased, and owing to antagonistic effect, the content of cadmium in rice is decreased, and damage of human bodies due to harmful elements is reduced at the premise of supplementing trace elements necessary to human bodies.
Description
technical field [0001] The invention relates to the field of foliar fertilizer, in particular to a rice foliar fertilizer rich in five trace elements of boron, molybdenum, selenium, chromium and cobalt, and also relates to the application of the rice foliar fertilizer. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the cells on the surface. It can protect the mesophyll cells under the epidermis to perform photosynthesis, respiration and other functions, and not be affected by changes in external adverse conditions. There are many tiny pores on the surface of the leaves, which perform the function of gas replacement. The use of foliar fertilization can make nutrients quickly Enter the plant body ...
