Cultivation method for interplanting soybeans in newly planted sugarcane fields

Abstract

The invention relates to the technical field of plant cultivation, in particular to a cultivation method for interplanting soybeans in newly planted sugarcane fields. The cultivation method particularly includes simultaneously cultivating sugarcanes and the soybeans in the newly planted sugarcane fields in February every year; interplanting two rows of soybeans between each two adjacent rows of sugarcanes during cultivation, and applying solid water to the sugarcanes and the soybeans after seeds are sown. The solid water is formed after drought-resistant and water-absorbent polymers absorb moisture with the volume 200-300 times the volume of the drought-resistant and water-absorbent polymers. The cultivation method has the advantages that owing to the solid water capable of continuously releasing the moisture for up to 1-2 months, the sugarcanes and the soybeans can be simultaneously planted early, prompt soybean harvesting is unaffected, a high germination rate and a high seedling rate of sugarcane seedlings can be guaranteed, and the purpose of double good yields of the sugarcanes and the soybeans in the newly planted sugarcane fields can be achieved; by the aid of the cultivation method, the land utilization rate can be effectively increased, the crop yield can be increased, and the economic benefit can be improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method for interplanting soybeans in newly planted sugarcane fields. technical background [0002] The sugarcane growth cycle is long, the row spacing is large, and the row closure is late. Making full use of this time to interplant other short-term crops in the sugarcane row can increase the multiple cropping index of sugarcane land, improve land utilization, and increase crop yield and economic benefits. At present, some people have interplanted watermelons, potatoes and other crops in sugarcane fields, all of which have achieved good economic benefits. [0003] Chen Guiqin published an article titled "Sugarcane Field Interplanting Soybeans Benefits Good" in the 02nd issue of "Friends of the Farm" in 1999. The article describes interplanting two rows of soybeans between rows of sugarcane in the perennial cane field in the middle and late March to obtain...

Problems solved by technology

At present, the technology is limited to interplanting in ratoon cane fields, and it is not suitable for interplanting in newly planted sugarcane fields

The reason is: when sugarcane grows vigorously in mid-to-late June and requires a lot of nutrients and large soil, soybeans must be harvested; In the field, February is the driest season of the year. Due to the constraints of water resources, economic capacity and labor force, sugarcane is planted in February. Naturally, sugarcane species are affected by drought, and shortages of seedlings and broken ridges abound. This in turn affects the yield of sugarcane

If the two crops cannot be planted at the same time and are proposed to be planted separately, the subsequent planting will inevitably affect the crops planted in the previous period.

Therefore, if there are no good technical measures, the effect of interplanting soybeans in newly planted sugarcane fields is not ideal
