The Winter green grape fertilization is an important part of grapevine production management in a year, so it is imperative to exert good winter fertilizer. The existing fertigation points of the green grapes in winter are described as follows:
Deep-dipping fertilization and deep-dipping fertilization can improve soil permeability, increase fertility levels, and promote root growth. Through the deep increase of organic fertilizer, formula fertilizer, to achieve balanced fertilization. From late October to early November of each year, the decomposed goats, cattle, and other livestock manure are evenly spread on the grape plots. Be sure to break up the large manure and pay attention to keeping the manure about 10 cm away from the vine. Left and right, then deepen the entire site, with a depth of about 6 to 8 cm.
Digging a trench and fertilizing a hedgerow digs 30 to 45 centimeters wide and 30 to 45 centimeters deep. Wherever the roots are excavated, no matter the size of the root system, they are cut off. Digging ditch 50 to 70 centimeters away from the trunk, digging one line at a time, digging each year. Then layer the fertilizer, the first layer is first filled with straw or decomposed sheep, cattle and other livestock manure, fill in the topsoil; the second layer is applied to organic fertilizer, added formula fertilizer, and then fill the subsoil.
Shallow excavation of the soil in the garden field should be properly dug shallow, its depth can not exceed 5 cm, easy to cover the film in the coming year.
