Embodiment 1

[0030] (1) Select high-yield, high-sugar, and fast-growing Guitang No. 40, Guitang No. 42, Guitang No. 47, Guitang 49 and other varieties of good and healthy first-class seedling stems, cut into two buds, and put them in snakeskin bag;

[0031] (2) The specific degree of deep plowing required for soil preparation must be adapted to local conditions, with a plowing depth of 30-40 cm, and a plowing layer that is deep, loose, broken, and flat;

[0032] (3) Open the planting ditch, and open the planting ditch according to the row spacing of 120 cm. The ditch depth is required to be 25-30 cm, the ditch bottom width is 20-25 cm, the ditch bottom is flat, and the soil is finely broken;

[0033] (4) When planting, the stems and the row grooves are arranged in a single row at 45 degrees, and the buds are on both sides. The sugarcane seeds should be in close contact with the soil, not overhead, and the stems should be covered with crushed soil immediately after planting;

[0034] (5) R...

Embodiment 2

[0040] Conventional sugarcane planting methods are as follows:

[0041] (1) The plowing depth of the land preparation should be more than 30 cm, and the plowing layer should be deep, loose, broken, and flat; the specific deep plowing degree must be adjusted according to local conditions, depending on the depth of the original plowing layer and the soil properties. Deep plowing should not destroy the original soil layer, and it should be combined with increasing fertilizer application.

[0042] (2) Planting furrows: The planting furrows should be opened according to the row spacing of 120 cm. It is required that the depth of the ditch is 25-30 cm, the width of the bottom of the ditch is 20-25 cm, and the bottom of the ditch is flat and finely broken.

[0043] (3) planting

[0044] The seed stems are arranged in two rows in the shape of a character, with buds on both sides. The sugarcane seeds should be in close contact with the soil, not overhead, and the seed stems should be co...

Abstract

The invention provides a method for improving a saccharum officinarum seed stem breeding yield and harvesting the saccharum officinarum in advance. The method comprises the following steps: step A, selecting one-level seed stems of healthy seed seedlings, and cutting the stems into segments for usage; step B, preparing land, controlling the tilling depth to be 40cm or more, digging planting furrows with a row spacing of 120cm, a furrow depth of 25-30cm, and a furrow bottom width of 20-25cm, wherein the furrow bottom is smooth, and soil is loosened, smashed and fine; step C, sowing the seed stems, allowing buds to face to two sides, and covering the seed stems with smashed soil; step D, performing thick planting reasonably; step E, after seed stem planting and earthing are finished, preparing a weed killer mixed liquid by adopting 600mL of 80% acetochlor emulsifiable concentrate and 750-1125kg of water, and spraying the weed killer mixed liquid to the planting furrows uniformly; step F, before intertillage and hilling, uncovering a membrane, and in an intertillage stage, applying urea topdressing, and performing hilling; and step G, in a tillering last stage, mixing 3g of gibberellin , 300g of calcium nitrate, 200g of potassium nitrate, 60g of boric acid, 35g of a sugarcane borer removing agent, and 200mg of prochloraz, and dissolving the above mixed materials in 600-800mL of water. The method provided by the invention can promote saccharum officinarum growth and development, the saccharum officinarum can be harvested 6-10 days in advance, and the seed breeding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural economic crop planting, and in particular relates to a method for increasing the yield of sugarcane stem breeding and harvesting in advance. Background technique [0002] Sugarcane is a perennial tall solid herb, rich in sugar and water, and also contains various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism. It is mainly used for sugar production. plays an important role in. Sugarcane is asexually propagated and has a low reproduction coefficient. About 5 mu of sugarcane breeding stems can be planted for one mu of sugarcane breeding stems. However, the planting area of ​​sugarcane in my country is more than 20 million mu. If you want to upgrade and promote new varieties, you need to form a certain scale to be able to To achieve the purpose of increasing the speed of promotion. Moreover, the breeding of sugarcane seed...
