Embodiment 1

[0007] Example 1: with 1% KH 2 PO 4 Soak 200g Jatropha jatropha in 2L of solution for 24 hours, sow 200m of soil with a thickness of 20cm 2 In the seedbed, the pH value of the soil is 6.5-6.7, 1000kg of decomposed domestic waste (including cushion and covering layer on a dry basis), the temperature of the seedbed is 5-20°C, and the water content of the seedbed before germination is 22-25%. The water content is 16-18%. After 45 days, 41,881 seedlings with more than 4 true leaves were obtained, with a seedling rate of 96.8%, and 39,787 seedlings with a height of 1.2 to 1.5 m were obtained after transplanting to a nursery for 7 months at a plant spacing of 30×30 cm.

Embodiment 2

[0008] Embodiment 2: with 1.5%KH 2 PO 4 Soak 5kg Jatropha jatropha in the solution for 30 hours, sow 2000m 2 In the field seedbed, the soil pH value is 6.2-6.5, 8000kg of decomposed plant residues are applied (on a dry basis, including cushion and covering layer), the temperature of the seedbed is 2-25°C, and the water content of the seedbed before germination is 20-28%. The final water content is 15-18%. After 2 months, 1.04 million seedlings with more than 6 true leaves were obtained, with a seedling rate of 96.2%, and 990,000 seedlings with a height of 0.4 to 1.2 m were obtained after transplanting to a nursery with a plant spacing of 20×20 cm for 7 months.

Abstract

A method for culturing mallotus saplings includes such steps as immersing the seeds of mallotus in the solution of KH2PO4 for 8-48 hr, sowing on seedbed, culturing, and transplanting to nursery.

Description

technical field [0001] The invention relates to a breeding method of Jatropha tomentosa Background technique [0002] Idesia Polycarpa Var.Vestita Diels is a variety of Idesia Polycarpa Var.Vestita Diels, a deciduous tree. It is a high-quality woody edible oil plant. The unsaturated fatty acid content of its oil is greater than 80%, linoleic acid The content reaches about 70%, the vitamin E content is greater than 1‰, and has no poisonous and harmful ingredients. The oil content of the fruit is 38-42%. In the prolific period (more than 40 years), the fruit yield per mu can reach more than 1800kg. The root system of Jatropha magnolia is well developed, and the function of water and soil conservation is strong. The trunk is straight, pagoda-shaped, and the fruit is bright red, which has good ornamental value. The wood texture is fine, not easy to deform, hard and resilient. Jatropha Maoye is basically in the wild at present, mainly distributed in the Yangtze River Basin, ...
