Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see figure 1 , the invention provides a short stem planting method of cassava, comprising the steps of:

[0019] 1) Selection and processing of seed stems: including seed selection: cassava is usually propagated by stems, wherein the lower section of the main stem has strong germination power, strong germination, neatness, and high yield, which is better than the middle section, and even better than the slightly section and branch sections; The old ste...

Abstract

The invention discloses a planting method for short stems of cassava. The planting method comprises the following steps: selection and treatment of seed stems, deep ploughing and soil preparation, planting, grain management and cassava harvesting. The general standard of selection of seed stems in the step 1) is that the seed stems is round and thick, has dens nodes, has no disease or pests, has no damage, and has bright color, the seed stem is fresh, when the seed stem is cut off, a milky liquid outflows, and the bud points are round and obviously prominent. The main diseases and pests in thedisease pest control in the step 4) are bacterial wilt, bacterial angular leaf spot, brown angular leaf spot, damage caused by pests and damage caused by rats. The lowest temperature of cassava germination is 14-16 DEG C, the cassava can grow normally at 18-20 DEG C, and the optimum temperature is 25-29 DEG C; the optimum temperature for tuberous root expansion is 22-25 DEG C, the temperature ofhighest photosynthetic efficiency is 40 DEG C, and the temperature of lowest photosynthetic efficiency is 14 DEG C. According to the planting method provided by the invention, through reasonable management on cassava, reasonable fertilization, and timely and effective prevention and treatment on disease and pests, the yield and the economic benefit of the cassava can be effectively improved.

Description

technical field [0001] The invention relates to the field of polarizers, in particular to a method for planting short stems of cassava. Background technique [0002] Cassava, erect shrub, 1.5-3m high; tuber cylindrical. Leaves are papery, nearly round in outline, palmately parted almost to base, 3-7 lobes, oblanceolate to narrowly elliptic, apex acuminate; petiole 8-22 cm long, slightly peltate, with Inconspicuous slender edges; stipules triangular-lanceolate, entire or with 1-2 setae-like lobes. Inflorescences terminal or axillary, bracts strip-lanceolate; calyx purplish red with white powder frost; male flowers: calyx about 7 mm long, lobes long ovate, nearly equal in size, inner surface hairy; stamens 6-7 mm long mm, anther top covered with short white hairs; female flower: calyx about 10 mm long, lobes oblong-lanceolate, stigma curved outward, fan-shaped. Capsule elliptic, surface rough, with 6 narrow and wavy longitudinal wings; seeds about 1 cm long, somewhat triang...
