A kind of sugarcane healthy seedling bud eye seedling raising and its mechanical transplanting method

Abstract

The invention discloses a sugarcane healthy seedling bud eye seedling and a mechanical transplanting method thereof. The method comprises the following steps of cutting the sugarcane healthy seedlingbub eye from a sugarcane stem, sterilizing, cultivating the bub eye in a seedling tray to grow to 4-5 pieces of true leaves, and then transplanting into fields by machinery. The method can obtain sugarcane seeds while the sugarcane stem is still a whole sugarcane stem, can continue to enter a sugar house for sugar extraction, and greatly save the sugarcane stem; the sugarcane healthy seedling budeye are cut and then subjected to nutrient seedling cultivation and then transplanted by the machinery, sugarcane bud rate and transplant survival rate are high, and the method can quickly get sugarcane seedlings, be suitable for large-scale planting of sugarcane, greatly reduce the cost of sugarcane cultivation and improve the planting efficiency of the sugarcane.

Description

technical field [0001] The invention belongs to the technical field of plant seedling raising and planting, and in particular relates to a healthy sugarcane seedling seedling raising and a mechanical transplanting method thereof. Background technique [0002] Cane sugar industry is one of the important advantageous industries in Guangxi, which plays a decisive role in the balance of supply and demand of sugar in our country. Since the "Eleventh Five-Year Plan", Guangxi's sugarcane production has achieved rapid development, with simultaneous growth in planting area, per unit yield and total output. The overall scale of Guangxi's cane sugar industry has reached the first place in the country, and its dominant position in the country has become increasingly prominent. However, insufficient supply of sugarcane seeds, single sugarcane varieties, degraded species, and low yield per unit area are still bottlenecks affecting the development of the sugarcane industry; Weakness and s...

Problems solved by technology

[0003] Although the tissue culture of sugarcane seedlings has been rapidly promoted since the rise of sugarcane seedlings, which has played a certain role in alleviating the serious shortage of sugarcane seeds, but the cost of tissue culture is relatively high, and the requirements for technology and conditions are relatively high. Therefore, the current sugarcane production Most of the planting and breeding are planted with sugarcane seeds or single buds of sugarcane or transplanted after seedling cultivation

At the beginning of sugarcane planting, the whole cane stem is taken, cut into sections with double-bud stems, and then planted horizontally or obliquely. Seed degradation and yield reduction make sugarcane growers less profitable

In order to reduce the cost of sugarcane seeds, sugarcane farmers later changed the double buds to single buds. However, in order to ensure that the sugarcane seeds can provide enough nutrients for the germination and growth of single buds, the stems of single buds are still longer. , the whole sugarcane is hardly left, and the waste of cane stems is still very large, and the sugar factory does not like to buy the small pieces of sugarcane stems remaining after cutting the seeds.

Therefore, when the cane stalks are harvested every year, a part of the cane stalks must be reserved for separate seeding. The remaining part of the cane stalks cannot be sold to the sugar factory to squeeze sugar, which reduces the income of the sugarcane growers, resulting in a reduction in income if more seeds are reserved. Less seedlings are kept for breeding, and there are fewer new seedlings for breeding. The perennial roots of sugarcane in some sugarcane fields have not been refurbished for many years, and the yield of sugarcane is low.

[0004] With the expansion of sugarcane planting scale, sugarcane planting has also realized mechanical sowing, and the degree of mechanization is gradually improving. However, most of the sugarcane plants that use sugarcane seeds and use machinery to plant sugarcane are directly sowing the seed stems in the field. low germination rate

It is rare to plant the seedlings by planting stems first, and then sow them mechanically, because the seedlings generally cultivated are not suitable for mechanical sowing
