Problems solved by technology

[0005] The technical problem to be solved in the present invention is to overcome the rapid growth of Jatropha curcas in the prior art, the excessive consumption of soil nutrients by planting Jatropha curcas alone, increasing the cost of artificial nutrition supplementation and the serious damage of plant diseases and insect pests caused by the single planting of Astragalus membranaceus The defect of low yield, its purpose is to provide a method to effectively play the ecological benefits of the two crops and increase crop yield and output value for the construction of a large-area raw material production base for Jatropha curcas

Embodiment 1

[0036] Follow the steps below

[0037] 1. Seedling raising: In March, open a 5cm deep shallow ditch on the surface of the well-arranged seedling raising field, the distance between the ditch (row spacing) is 20cm, sow Jatropha seeds on demand at a plant spacing of 10cm, cover the soil until the surface of the box is flat, water thoroughly, and the seedling tube After 3 months of transplantation.

[0038] 2. Preparation for interplanting: dig a Jatropha planting pond of 40×40×40cm according to the row spacing of 200cm×300cm, and leave 5cm of loose soil at the bottom of the pond; open 10cm-15cm deep film pods between the rows of Jatropha curcas at a row spacing of 50cm Astragalus is planted in shallow furrows in 3 rows.

[0039] 3. Interplanting: Jatropha curcas is planted in a pond of 40×40×40cm, and the planting depth is arranged according to the size of the seedlings. It is advisable that the base of the seedling root is 5cm lower than the pond surface, and the root system t...

Embodiment 2 and Embodiment 3

[0049] Embodiment 2 and embodiment 3: except that high-efficiency compound fertilizer: calcium superphosphate fertilizer is applied to the amount of basal fertilizer and topdressing fertilizer, and the amount of species of Astragalus membranaceus is different, all the other operating methods are the same as in embodiment 1, and will not be repeated. See Table 1 for the differences.

[0050] Table 1 Operational Differences and Effects of Embodiment 1, Embodiment 2 and Embodiment 3

[0051]

Embodiment 4

[0052] The test of embodiment 4 Astragalus membranaceus single species

[0053] The test of the single species of Astragalus membranaceus, its planting time, row spacing, management, fertilization, topdressing and fertilizer used, dosage etc. are all the same as the planting method of Astragalus membranaceus in Example 1, no more details, single species of Astragalus membranaceus The production details are shown in Table 2.

Abstract

The invention discloses a method for intercropping astragalus membranaceus and jatropha curcas, belonging to the technical field of crop planting. The method comprises the following steps: the astragalus membranaceus is planted at April to May of every year under the conventional planting mode of the jatropha curcas; the astragalus membranaceus is planted with the row space of 50cm to 55cm in theline of the jatropha curcas in same field; the seed-using amount of the jatropha curcas is 1000 to 1500g, and the planting distance thereof is 10cm to 12cm; the additional fertilizer consists of high-effective compound fertilizer and superphosphate fertilizer with the ratio of 1:2 to 5; and the applying amount of the additional fertilizer in every mu is 10 to 15kg. The planting mode effectively exerts the diversity of biological species when two types of crops with different subject categories and different plant height are interplanted, supplies nutrients to the jatropha curcas, reduces the occurrence of pest and disease damage, thus increasing the yield and production value of the two types of crops, leading the astragalus membranaceus to increase the yield by 50kg / mu than monotypic planting and leading the jatropha curcas seeds to increase the yield by 40kg / mu than monotypic planting.

Description

technical field [0001] The invention relates to the technical field of planting forest crops, in particular to a method for interplanting Astragalus membranaceus and Jatropha curcas. Background technique [0002] Jatropha curcas (Jatropha curcas) is a drought-resistant, barren-resistant perennial, multi-purpose tree species. Planting Jatropha curcas can not only increase vegetation and improve the ecological environment, but its seeds and sap are used in medicine, chemical industry, protein feed, etc. have wider applications. In particular, the crude fat mixture of seeds can be transformed into an ideal environment-friendly mechanical fuel oil. [0003] Astragalus membrane pod (Astragalus membranaceus (Fisch.) Bge.) is a perennial herbaceous plant of the leguminous family. It grows in hillside shrubs and sandy loam areas on dry slopes. It is an important medicinal material species in my country's Pharmacopoeia. [0004] At present, Jatropha curcas has been artificially pla...
