Problems solved by technology

In the greenhouse environment, the growth period can be advanced, but the jointing of lettuce grows in winter, and the low temperature resistance is weakened. In case of frosty weather, the young leaves at the top growth point of the lettuce during the growth process are vulnerable to freezing damage, causing sclerotinia and gray mold Infection through wounds causes leaves and fleshy stems to rot, thus affecting the quality of lettuce

Abstract

The invention relates to a nutrient fertilizer of lettuce. The nutrient fertilizer comprises rabbit manure, potassium dihydrogen phosphate, sulfuric acid, zinc sulfate, sodium molybdate, manganese sulfate, ammonium nitrate, coal slag, tobacco rods, spent mushroom compost, urea, crop straw, paclobutrazol, gibberellin and bentonite. Application of the nutrient fertilizer as a base fertilizer in one time not only can guarantee the nutrient elements necessary for the whole growth period of lettuce, but also can simultaneously kill germs, and can effectively prevent sclerotinia and botrytis infection. Thus, the nutrient fertilizer provided in the invention plays an active promotion role in raising lettuce quality.

Description

technical field [0001] The patent of the present invention relates to a fertilizer, in particular to a nutrient fertilizer for lettuce. Background technique [0002] Lettuce, Asteraceae, Lactuca, one or two annual herbaceous plants. Lettuce can be divided into leaf and stem. There are many names of lettuce, which are called "thousand gold vegetables", "lettuce" and "stone lettuce" in the cursive script. Leaf lettuce is also called spring vegetable and lettuce, and stem lettuce is also called lettuce and fragrant bamboo shoots. The cultivated area of ​​lettuce is more than that of lettuce in various parts of our country. The meat of lettuce is tender, and the stems can be eaten raw, cold, fried, dried or pickled. Lettuce mainly eats leaves or leaf bulbs. In recent years, it has developed in major cities, especially in the southern coastal provinces, and has become the main vegetable for increasing fancy varieties. Lettuce stems and leaves contain lettuce, which is bitter...
