Problems solved by technology

Because Jatropha is a tall shrub and arbor species, the understory area between the row spacing of cultivated plants is often only weeds, which not only brings too much weeding cost for field management and protection, but also the land is not fully utilized, an

Embodiment 1

[0021] Embodiment 1: carry out according to the following steps

[0022] 1. Seedling raising: In March, open 5cm deep shallow trenches on the surface of the well-arranged seedling raising field, the distance between the trenches (row spacing) is 20cm, and the jatropha seeds are sown on demand at a distance of 10cm. month transplant.

[0023] 2. Preparation for interplanting: Open a 50cm-wide flat strip along the contour line of the planting plot. The distance between the centers of the strips is 300cm as the row spacing, and a Jatropha planting pond of 40×40×40cm is dug at a plant spacing of 200cm. Loosen the soil at 10 cm; dig two roselle planting holes of 5 × 5 × 5 cm between the Jatropha plants with a plant spacing of 50 cm.

[0024] 3. Interplanting: Jatropha is planted in a pond of 40 × 40 × 40cm, and the planting depth is arranged according to the size of the seedlings. The root base of the seedlings is 5cm lower than the pond surface, and the excessively long roots are...

Embodiment 2 and Embodiment 3

[0032] Embodiment 2 and embodiment 3: except that high-efficiency compound fertilizer: calcium superphosphate fertilizer is applied into base manure amount and topdressing fertilizer amount are different, all the other operating methods are all the same as embodiment 1, are not repeated. See Table 1 for the differences.

[0033]

[0034]According to the above examples, the roselle is harvested in the year of growth, and through yield measurement, the average harvested dry goods (calyx) is 51.3kg per mu. Calculated at the price of 40 yuan per kilogram, the annual economic income per mu will increase by 2052 yuan.

Abstract

The invention discloses a method for interplanting roselle and jatropha, which belongs to the technical field of planting of forestry and agricultural crops and includes seedling raising, interplanting land preparation, interplanting, management, seed harvesting and calyx harvesting. An interplanting land is a flat strip land 50cm in width, center-to-center spacing 300cm of strips serves as row spacing, a jatropha planting pond is dug according to a plant spacing 200cm, and two roselle planting holes are dug between each two jatropha plants according to the plant spacing 50cm; compound fertilizer is applied around each jatropha seedling and 5-15cm away from the jatropha seedling during planting; base fertilizer is composed of calcium superphosphate fertilizer in a proportion of 1:2-5, roselle seeds are directly sowed in the holes 5X5X5cm, and two to three seeds are sowed in each hole; and additional fertilizer is applied 90 days after planting of jatropha, additional fertilizer is applied when roselle grows for about 45 days, and the additional fertilizer is equal to the base fertilizer in terms of ingredients and content. The method can be used for developing biodiesel, and by the method, 45-50kg of dry calyx of roselle can be harvested per mu averagely, and economic income is increased by 1800-2000 yuan.

Description

technical field [0001] The invention relates to the technical field of planting forest crops, in particular to a method for interplanting roselle and jatropha. Background technique [0002] Jatropha ( Jatropha curcas ) is a drought-resistant, barren-resistant perennial, multi-purpose tree species, widely distributed in tropical or subtropical regions, mainly produced in America and tropical Africa. my country is mainly distributed in Yunnan, Sichuan, Guangxi, Guangdong, Hainan and other places, with the most in Yunnan, followed by Sichuan. Planting jatropha can increase vegetation and improve the ecological environment. Its seeds and sap are widely used in medicine, chemical industry, protein feed, etc. In particular, the crude fat mixture obtained by pressing from seeds can be further chemically transformed to obtain an ideal environmentally friendly mechanical fuel, called biodiesel. [0003] Roselle ( Hibiscus sabdariffa ) is an annual herb or perennial shrub of th...
