The ecological conditions of Zaoyuan are relatively stable, and there is a relatively large space suitable for weed growth. Due to the differences in site conditions, management levels, and climatic factors, the distribution characteristics and types of weeds are quite different. In summer and autumn, high temperature and high humidity, more hot weeds, and rapid growth, great harm; winter and spring low temperature and drought, less weeds, and less harmful. The intensive cultivation of Zaoyuan and Jujube Grain Intercropping Zaoyuan mainly include annual weeds; the management of extensive Zaoyuan uses mainly perennial weeds; the soil fertility is high and the irrigation conditions are good; the broad-leaved weeds predominate, and vice versa. Grass dominates. Jujube weed vigorous growth will compete with jujube trees for water and nutrients, shade the sun, affect the photosynthesis of jujube trees. Therefore, the jujube garden weeds must pay attention to timely control, control its prosperous long, change grass damage is grass benefits. Zaoyuan weeds are characterized by diversity and complexity, different types of weeds have different biological characteristics, and the regularity of growth and decline is different. The management level of date gardens is different. Therefore, to control the damage of weeds, we must adapt measures to local conditions and adopt appropriate measures to make weeds harmless.
1. Cultivate the weeds in the clear tillage method: In the spring, the clear cultivation method of Zaoyuan should be adopted. Manual weeding or mechanical weeding is beneficial to the preservation of loquat orchards, increase the low temperature and promote the growth of jujube trees. In order to eliminate weeds by clearing cultivation, weeding should be carried out at the peak of weeds emergence in accordance with the principle of “except small additionâ€.
2. Membrane-based control of weeds: In spring, covered with black mulch under the tree can effectively prevent the growth of weeds. At the same time, it can also prevent the evaporation of soil moisture, protect the pupa; improve the temperature to promote the early growth of jujube shoots; to prevent the soil from overwhelming the source of bacteria, and reduce pest damage.
3. Chemical control of weeds: In summer and autumn, weeds thrive and the use of herbicides for weed control is the simplest, most effective, and quickest method. If you use gram-free herbicide, it can be effective in half an hour, which is better than manual weeding, labor saving, time saving, saving of funds, and effective results.
4. Intercropping control weeds: jujube saplings, intercropping crops or pastures, is an active method of soil tillage and weed control. The intercropping of soybeans or pastures in the jujube garden makes the germination of weed seeds in a shaded state. Some seeds do not sprout, even if the sprouting seedlings are in a malnutrition state and grow poorly, thereby reducing the growth of weeds and effectively controlling weeds. Occurs to achieve intercropping purposes.
5. Breeding methods to control weeds: The jujube gardens are free-range geese, ducks, chickens and other ecological methods for the control of weeds. The geese, ducks, and chickens under the tree can eat grass and eat worms, which can reduce the cost of the grass in the jujube garden, produce manure and soil in the poultry, facilitate the high yield of jujube trees and improve the quality of jujube fruits. , ducks, chicken breeding benefits.
6. Coverage control weeds: summer and autumn seasons, to promote the Zaoyuan ground cover. Straw, green manure, weeds, etc. can be used as coverings. The method of covering has no-tillage and grass-removing effect, and it can also keep the soil temperature constant in the hot summer season, which is conducive to the growth and absorption of the roots, thereby realizing the high yield of the jujube tree. In addition to saving weeding labor and reducing production costs, under-tree coverings can also increase soil fertility.
7. Grass weeds control weeds: At present, jujube trees are planted, and weeding methods are advocated. The intensive cultivation method takes time and labor, and weeding consumes a lot of manpower. By using the weeding method, one can achieve the ecological diversity of the jujube garden, protect a large number of beneficial insects, and prevent the harmful insects from exploding; secondly, it can achieve windproof and sand-fixing in the winter and the effect of preventing water and soil loss during the rainy season; thirdly, when weeds thrive in summer and autumn, Using a lawn mower for weeding, high work efficiency. Mechanical cutting twice or three times a year, as well as cutting green grass to cover the tree disk, can also increase the soil fertility; Fourth, it can effectively reduce the surface temperature in the summer and autumn high temperature season, is conducive to root growth.
