Corn albino seedlings are a common seedling disease in corn production. A white albino seedling shows a white seedling as soon as it is unearthed. This is a genetic phenomenon known as the lethal gene albino seedling. It cannot be self-supported due to lack of chlorophyll and soon died. Another albino seedling, the occurrence of symptoms generally begins at the 4th leaf stage of the maize, the leaf color of the base of the leaf becomes light, and the leaves of the leaf appear pale yellow and light green between 5 and 6 leaves, but the veins are still green and the base appears. Purple streak, after 10 to 15 days, purple gradually turned yellow-white, leaf meat became thin, was "white seedlings." When serious, the whole field is white. Mainly due to lack of zinc in soil. Zinc-deficient corn plants are dwarf, with short internodes and leafy clusters. In severe cases, the leaves are dry and even granules are not harvested. Control methods: (1) The occurrence of the first kind of corn albino seedlings is controlled by genetic genes, which has little effect on the economic value of corn. However, in the selection of new corn varieties, we must pay attention to selection. (2) The second prevention measures for corn albino seedlings caused by zinc deficiency in soil: Use lkg zinc sulfate and 10 ~ 15kg fine soil mixed evenly, when sowing in the next to the seed or with zinc sulfate 0.75-1kg / acre and diammonium or compound fertilizer evenly do seed fertilizer; also available zinc seed dressing, with 0.04- 0.06 kg zinc fertilizer, 1 kilogram of water, 10 kilograms of seed dressing, boring 2 to 3 hours, dried after sowing; for the emergence of albino seedlings of corn, with 0.2 ~ 0.3kg of zinc sulfate to 100kg of water spray per acre; 7 days spray 1, even spray 2 or 3 times.
