CN-122004000-A - Wild green manure planting method for improving organic matter content of Gannan navel orange garden soil in slope farmland

Abstract

The invention relates to a wild green manure planting method for improving soil organic matter content of Gannan navel orange gardens of slope cultivated lands, which comprises the following steps of S1, obtaining wild green manure crops, wherein the green manure crops comprise at least one of oxalis, centella asiatica, chickweed, herba violae and herba Erodii seu Geranii, S2, planting Gannan navel oranges in a target garden, and then planting the green manure crops to finish green manure planting. According to the technical scheme, one of the oxalis, centella asiatica, chickweed, viola philippica and herba et Gemma Agrimoniae is adopted as the green manure, so that artificial cultivation and management are not needed in long-term soil management, and the development period of plants can be completed repeatedly under natural conditions. The wild green manure crop of this scheme is ecological strong adaptability, and the management cost is extremely low, can effectively break through the bottleneck that green manure industry developed in hillside fields orchard, provides the new thinking for the popularization of Gannan navel orange garden soil carburetion fertilizer cultivation obstacle-removing technique.

Description

Wild green manure planting method for improving organic matter content of Gannan navel orange garden soil in slope farmland Technical Field The invention relates to the technical field of plant planting, in particular to a wild green manure planting method for improving organic matter content in soil of Gannan navel orange orchard in slope farmland. Background How to effectively prevent and treat water and soil loss, reduce nutrient loss, improve cultivated land quality and ecological environment of the Gannan navel orange garden in slope cultivated lands is particularly important to ensure high-quality production of navel oranges. The grass growing cultivation is used as a mode for effectively inhibiting water and soil loss and soil degradation of a hillside orchard and simplifying fertilizer cultivation lightly, and has important application potential. However, the conventional green manure for the Gannan navel orange garden in the slope cultivated land has weak ecological adaptability and high planting cost, and the popularization of the cultivation of the grass is directly limited due to frequent occurrence of malignant weeds in the natural grass. The green manure industry of the navel orange in Gannan is developed to have better utilization potential and application value, and a new solution is needed to be explored. Disclosure of Invention Based on the expression, the invention provides a wild green manure planting method for improving the organic matter content of the soil of the Gannan navel orange garden in the slope farmland, aiming at solving the problem of water and soil loss of the Gannan navel orange garden in the slope farmland. The technical scheme for solving the technical problems is as follows: the invention provides a wild green manure planting method for improving soil organic matter content of a Gannan navel orange garden in a slope farmland, which comprises the following steps: S1, obtaining a wild green manure crop, wherein the wild green manure crop comprises at least one of oxalis, centella asiatica, chickweed, viola philippica and herba et Gemma Agrimoniae; S2, planting the wild green manure crops after planting the Gannan navel oranges in the target park, and finishing green manure planting. Further, the green manure crop is oxalis, and the sowing amount of the oxalis is 15.0-22.5 kg/hm 2. Further, the green manure crop is centella asiatica, and the plant row spacing of centella asiatica is 20-40 cm. Further, the green manure crop is chickweed, and the sowing amount of the chickweed is 15.0-22.5 kg/hm 2. Further, the green manure crop is herba Violae, and the sowing amount of the herba Violae is 15.0-22.5 kg/hm 2. Further, the green manure crop is the wild crane grass, and the sowing amount of the wild crane grass is 22.5-30.0 kg/hm 2. Compared with the prior art, the technical scheme of the application has the following beneficial technical effects: (1) According to the technical scheme, one of the oxalis, the centella asiatica, the chickweed, the viola philippica and the herba et Gemma Agrimoniae is adopted as the green manure, artificial cultivation and management are not needed in long-term soil management, the development period of plants can be completed repeatedly under natural conditions, stable dominant groups can be formed within 1-2 years after sowing, and additional management is almost not needed in the following years. The wild green manure has strong ecological adaptability and extremely low management cost, can effectively break through the bottleneck of green manure industry development in hillside fields, and provides a new thought for the popularization of the Gannan navel orange garden soil carburetion fertilizer-culturing obstacle-removing technology. (2) The quality of dry matters of the leaves, scion stems, stock stems and roots of the navel orange saplings treated by the green manure is obviously higher than that of the navel orange saplings treated by natural grass, so that the wild green manure can effectively promote the growth and development of all organs of the navel orange saplings and enhance the nutrition synthesis and storage capacity of the navel orange saplings. Wherein, the total dry matter content of the green manure treatment of the wild geranium and chickweed is obviously higher than that of the natural grass treatment, and the advantages are outstanding.
