Problems solved by technology

[0004] Through investigation and research, it has been found that although wild tung tree grows in many areas, due to the special living environment of wild tung tree, there are generally problems such as poor tree shape and low seed yield when using propagated tung tree seedlings for artificial cultivation. It is unfavorable for seed oil extraction, or for fencing and ornamental use
In particular, the immaturity of intensive large-scale artificial cultivation technology has always plagued the development and utilization of tung tree

Embodiment Construction

[0020] See an example given below:

[0021] Use the stored seeds to artificially propagate the tung tree seedlings, sow in drills, lay the seeds flat, sow 50g of seeds per square meter of seedbed, cover with 2cm of soil, and emerge from the nursery within 1 year. Plant at a plant spacing of 1.5 meters and a row spacing of 2.5 meters. No fertilization is applied in the pit. Before planting, the leaves at the base of the tung tree seedlings are trimmed, leaving only 3-5 leaves at the tip of the stem. After planting, pour enough water for rooting. When the tung tree grows to a height of about 1.2 meters, start pruning and shaping, topping and topping, pruning into an inverted umbrella tree shape, and keeping the tree height at about 2.2 meters when blooming. Carry out fertilization and weeding, mainly nitrogen fertilizer or compound fertilizer in May, and organic fertilizer in October. The amount of fertilizer applied depends on the soil fertility and the size of the seedlings. ...

Abstract

The jatropha yield increasing and stabilizing cultivation process includes the following steps: growing seedling; transplanting; pruning and shaping through topping-off and shaping to form turned umbrella tree after the jatropha tree grows to 1-1.5 m height and maintaining the tree height during blossom of 2-2.5 m and fruit bearing all the year round; and applying balancing nitrogen fertilizer, phosphate fertilizer and potash fertilizer. The cultivation process has fast growth, increased and stabilized yield, low consumption and easy picking of jatropha fruit.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a cultivation method for stabilizing and high-yielding tung tree. Background technique [0002] Jatropha curcas L. is also known as Jatropha curcas and Jatropha curcas. Distributed in tropical and subtropical regions. my country has cultivated or semi-wild. Shrubs or small trees, 2-5m high, much branched, fast-growing. Like fertile soil, acid soil or calcareous soil are suitable for growth. Resistant to low temperature around 0℃ and light frost. Strong wind resistance. my country's South China Sea islands are distributed. Cultivated or semi-wild in Taiwan, Fujian, Guangdong, Qiong, Guangxi, Yunnan, Guizhou, Sichuan and other places. It is mostly cultivated for fences and for ornamental purposes. The seed kernel contains about 50% oil, which can be used as lubricating oil, soap making, etc., and can induce vomiting and diarrhea, but it is poisonous and...
