Background
Cymbopogon citratus (DC.) stapf belongs to Gramineae (Gramineae) and Cymbopogon Spreng, and perennial herbs have thin and weak stalks, clumpy growth, narrow leaves and nearly no hair on both sides and are white in powder. The citronella grass is produced in tropical and subtropical regions, is distributed in south China, but is not easy to spike and fruit, and common varieties comprise citronella grass in West India, citronella grass in east India and citronella grass. The lemongrass is pungent and warm in nature and has the effects of dispelling wind, dredging collaterals, harmonizing stomach, ventilating, restoring consciousness and promoting estrus.
Moringa Oleifera (Moringa Oleifera Lam.), also known as drumstick tree, miraculous tree and the like, belongs to Moringaceae (Moringaceae) Moringa (Moringa Adans.), tropical and subtropical deciduous woody vegetables and oil plants, is originally produced in India and Africa, can be eaten by leaves, flowers, tender buds, tender stems, tender pods and roots, has rich and comprehensive nutrition, is the best source of various nutrients such as plant protein, vitamins, folic acid, pantothenic acid, calcium, iron, selenium and the like, and has the medical health-care effects of treating hyperlipidemia, hypertension and diabetes, enhancing physical strength, inhibiting germs and the like. The moringa oleifera is a fast-growing tree species, has long main roots, is high-temperature resistant and drought resistant, has the optimal growth temperature of 25-35 ℃, can adapt to various soil types, can normally grow in sandy loam with the pH value of the soil in the range of 4.5-8, and is suitable for being planted in tropical and southern subtropical regions in China with the altitude of below 600 m. In recent years, due to the dramatic increase of the demand of the moringa oleifera, the price of the moringa oleifera raw material is also increased year after year, and the raw material supply is seriously insufficient. The tropical and subtropical regions such as Hainan, Yunnan, Guangxi and the like are the authentic horseradish tree producing regions, the produced horseradish trees have good quality, the horseradish tree industry is developed at a high speed by well spraying with the continuous improvement of the horseradish tree cultivation and management technology, and the development of the horseradish tree industry is seriously hindered by the shortage of land resources.
The agriculture and forestry composite operation can be called composite agriculture and forestry, mixed forestry agriculture or agricultural forestry and the like, and refers to the integration of a land utilization mode and a technical system for artificially arranging perennial woody plants and other cultivated plants or livestock animals together according to a certain time sequence in space on the same land management unit according to the principle of ecological economy. The existing research results at home and abroad show that the forest farm compound operation can improve the utilization rate of resources such as illumination, soil and the like, and can also improve the soil fertility by the aim of cultivating and fostering, thereby promoting the growth of forest trees, having remarkable economic benefit and increasing the income of farmers. Research shows that the moringa oleifera can be subjected to staged, batched and layered leaf collection from the last 5 th month to the last 6 th month, from the last 7 th month to the last 8 th month and from the last 10 th month to the last 11 th month, branches are harvested and dwarfed after the leaves are collected in the 11 th month, the height of tree stumps is kept to be 40 cm-75 cm for new buds to germinate in the next year, so that the moringa oleifera forest is low in forest stand closure degree and full in space illumination in rows during the growth period of the new buds in spring every year, crops are planted in the moringa oleifera forest, the aim of tending by ploughing is achieved, more agricultural products are obtained, and the land use efficiency is improved.

Comparative example 1:
a small plot of the same plot as in example 1 was a control plot of moringa oleifera plain, which was separately divided. The comparative example is consistent with the example 1 in the same land preparation and moringa planting density, and is different from the following point: the base fertilizer is a mixed fertilizer used in conventional planting, and is used for picking normal branches and leaves of the moringa oleifera without fine pruning and shaping.
Comparative example 2:
plots were prepared for the same plot as in example 4, for the individual lots of lemongrass. The comparative example shows the same manner as that of example 4 in the preparation of the lemongrass plot and the planting manner of the lemongrass, and is different from that of example 4 in that: the base fertilizer is a mixed fertilizer used in conventional planting.
The inventor conducts the combined management method for planting the lemongrass under the moringa oleifera forest and the planting method for the moringa oleifera and the lemongrass in the comparative example from 2016, 3 months to the Tan village and the Shang Zhen village in Tan Luo town in the western village region of Guangxi Nanning city, and the related data results are shown in Table 1.
TABLE 1 Table of the change of soil nutrient content in the annual average yield and point of application of Moringa oleifera and Cymbopogon citratus for 2 years
As can be seen from table 1, by applying the technology of the present invention, after 2 years of planting, the moringa oleifera and the lemongrass in examples 1, 2, 3 and 4 grow vigorously, the plants are healthy, no plant diseases and insect pests are caused, considerable moringa oleifera leaf yield and lemongrass harvest yield are obtained after harvesting, and good economic benefits are achieved; meanwhile, the diversity of plants is increased through compound operation, the land utilization efficiency is greatly improved, particularly, the effective N, P, K content of soil nutrients is greatly improved compared with that before compound operation, the soil structure is improved, and good ecological benefits are embodied.
Comparing the embodiments 1-3 with the comparative example 1, it is found that under the same soil climate and other conditions, the organic fertilizer used in the technology of the invention is lacked in the moringa planting process in the comparative example 1, the soil fertility is attenuated, even the effective P content is increased negatively, the moringa grows in the later period and is weak, and the branch and leaf growth amount is obviously reduced due to the lack of scientific pruning and shaping, and the yield of the tender cabbage and the mature fresh leaves is only about 1/2 of that of the embodiments 1-4. This shows that examples 1 to 3 using the technology of the present invention have a better eco-economic benefit than comparative example 1.
Comparing the example 4 with the comparative example 2, the results show that under the same soil climate and other conditions, the yields of the cedronella in the comparative example and the example are not obviously different, but the yield of the moringa oleifera planting in the comparative example 2 is lacked, and the economic benefit is obviously lagged behind that of the example 4; meanwhile, the content of soil nutrients in example 4 is improved well compared with that in comparative example 2, and the content of alkaline hydrolysis N, the content of available P and the content of available K are obviously improved. This shows that example 4 using the technology of the present invention has a much better eco-economic efficiency than comparative example 2.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
