Rain collecting and fertilizer applying method for trees

Abstract

The invention discloses a rain collecting and fertilizer applying method for trees, which comprises the following steps: planting contiguous trees with tractor roads between, and making ridges at the positions of the projections of the outer edges of tree crowns, wherein the ridges form a row of grooves in a traverse direction of the trees; digging water collecting pits near blow the outer edge of the projections of the tree crowns and above the grooves; covering the projections of the tree crows with plastic thin films, wherein the upper part of the plastic thin films are consistent with theupper outer edges of the projections of the tree crows and the lower part of the plastic films cover the grooves and the water collecting pits; and opening holes in the plastic films above the water collecting pits for collecting rain. In the invention, a rain-collecting, evaporation-resistance, leakage-resistance and multi-storage high-efficiency rain utilization system is formed by using the common plastic thin films, fertilizer and water can be fed at the same time with the water collecting pits, and the method has the effects of saving water and fertilizer, facilitating harvest, avoiding weeding and the like.

Description

Technical field [0001] The invention relates to an agricultural water-saving fertilization method, in particular to a rain-collecting fertilization method for trees, in particular to a rain-collecting fertilization method for mountain or sloping jujube gardens based on plastic film. Background technique [0002] Jujube is China’s largest dried fruit tree species and one of the most representative national fruit trees. The country’s cultivated area has reached more than 20 million mu, with an annual output of more than 3 billion kilograms. It is located in the Taihang Mountains of Hebei, and the Bohai Sea Saline Areas in Hebei and Shandong. In the Loess Plateau of Northern Shaanxi, the Lvliang Mountains of Shanxi, the sandy areas of the old course of the Yellow River in Henan, and many national-level impoverished counties, old revolutionary bases and ethnic regions in Xinjiang, Ningxia, Yunnan, Guangxi and other places, the income of the jujube industry accounts for more than 50% o...

Problems solved by technology

Taking Shanxi as an example, the average annual rainfall is 500 millimeters, but about 400 milliliters of rainfall is lost into the air by natural evaporation and runoff, and is lost outside the region. 100 milliliters, it is far from sufficient water source for crops during the whole growth period, especially in mountainous and sloping lands and other natural conditions, rainwater is used less efficiently. "storage" water harvesting agriculture has important practical significance
