Drought-resistant cultivation method for boehmeria nivea in hilly land

Abstract

The invention discloses a drought-resistant cultivation method for boehmeria nivea in a hilly land. The method comprises the following steps: (1), ditching to make compartments in the slope direction: ditching to make compartments in the direction parallel to the slope direction according to the tendency of the slope of the hilly land;(2), planting along contour lines: planting along the contour lines in the direction perpendicular to the slope direction according to the tendency of the slope of the hilly land at equal row spaces; (3), carrying out cross cultivation: planting the odd number of boehmeria nivea in one row, planting the even number of boehmeria nivea in the next row and planting boehmeria nivea at intervals, so as to enable the planted boehmeria nivea to be crossed triangularly; (4), applying fertilizer: according to the soil fertility level of the hilly land, for the hilly land with the per mu yield of 200 Kg of raw boehmeria nivea, applying 40 Kg of winter cultivation compound fertilizer to per mu of boehmeria nivea, and dressing 10 Kg of urea to per mu of boehmeria nivea for second-time cultivation and third-time cultivation in one year; (5), preventing and controlling pests: adopting dipterex, permethrin or other chemical pesticides for pest prevention and control; (6), harvesting early: compared with the plain and lake areas, since the hilly land is dry and barren, the growth period of boehmeria nivea cultivated in the hilly land is short and boehmeria nivea can be harvested 3-5 days earlier. The method is easy and simple and convenient to operate, and rainwater can be effectively enriched through cross cultivation. In the growing period of the boehmeria nivea, the stable yield and high yield can be realized by using rainfall more effectively.

Description

technical field [0001] The invention belongs to the technical field of stress-resistant cultivation of ramie, and more specifically relates to a drought-resistant cultivation method of ramie on a hillside. Background technique [0002] Ramie (Boehmeria nivea L.Gaud.) is a perennial bast fiber crop belonging to Urticaceae Ramie. It is a traditional Chinese characteristic economic crop. Its output and area account for more than 90% of the world. It is an important textile raw material and a best-selling product for exporting foreign exchange. [0003] China's ramie is mainly distributed in the Yangtze River Basin, and is generally harvested three times a year. The stems and leaves grow luxuriantly, the transpiration is large, and the water demand is high. Water shortage will seriously affect the growth and development of ramie, and ultimately affect the yield and quality. Due to the lack of irrigation conditions, ramie in mountain and hilly areas often suffers from severe red...

Problems solved by technology

The main problem exists: the concentration and timing of spraying drought-resistance agents requires rich experience and has a certain impact on the environment; although mulching straw has a better drought resistance effect, since ramie is planted on hillsides, the mulching straw needs to be obtained from other Local distribution and crushing, not easy to popularize and utilize

Deep intertillage also has a better effect of drought resistance, but this measure is often difficult to achieve after ramie is closed

Although mulching straw has a better drought resistance effect, because ramie is planted on hillsides, the mulching straw needs to be transported and crushed from other places, which is not easy to popularize and utilize.
