Xunong purple yam big-ridge two-row whole-process mechanized cultivation method

Abstract

The invention discloses a xunong purple yam big-ridge two-row whole-process mechanized cultivation method, belonging to a crop cultivation technique. Soil for cultivation is sandy soil, loamy soil or cohesive soil. Four machines, i.e. a rotary-tillage, ridging and inter-tillage all-in-one machine, a big-ridge two-row chain-spoon-type seeding machine, a climber cutting, crushing and returning-to-field machine and a multi-roller harvesting machine are selected and used to complete 10 major production processes, i.e. rotary tillage, ridging, seeding, inter-tillage, additional fertilizer application, insecticide application, weed control, hilling-up, climber cutting and harvesting. The xunong purple yam big-ridge two-row whole-process mechanized cultivation method has the beneficial effects that the soil types for yam cultivation are widened; the traditional cultivation modes of manual trench digging or mechanized trenching are abandoned and the cultivation system of digging deep trencheswhich seriously damage the soil plough horizon is changed; the situation that the trenches are collapsed on rainy days in summer is avoided; the whole-process mechanized cultivation of yams is realized without erecting supports and the problem that the yams are difficult to harvest is solved; and the mechanized cultivation technique is simple and feasible and easy to popularize, the labor intensity of yam growers is greatly reduced, the ecological balance of the soil plough horizon is protected and the total amount of saved cost and increased profit is more than 2500 RMB / mu.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a whole-process mechanized cultivation method of Xu Nong's purple medicine in two rows on large ridges. It is mainly used for light and simplified cultivation techniques of high-quality and high-efficiency economic crop purple yam. Background technique [0002] Yam ( Dioscorea opposita Thunb) belongs to Dioscoreaceae and is an annual or perennial winding herb. It has high nutritional value, medicinal value and economic value. It is also used as food, vegetable medicine and industrial raw materials. It is also one of the characteristic vegetable crops that earn foreign exchange through export in my country. Its economic output per unit area and protein output are more than twice that of rice, wheat and other food crops. It can be eaten cooked or raw, and has good health benefits. Yam was regarded as a small crop in the past, and there has been a lack of systematic res...

Problems solved by technology

Yam planting requires traditional manual ditching or mechanized pine ditch. The 1.5-1.8m deep ditch seriously damages the soil cultivation layer, and rut ditch phenomenon is very easy to occur when it is rainy in summer

At present, there is no yam harvesting machine suitable for popularization in the whole country, and the harvesting is still dominated by manual harvesting. Only some areas use high-pressure water guns to harvest (but they must be sold immediately and cannot be stored).

The key technical problems in the development of my country's yam industry are: (1) the lack of high-quality and efficient new varieties of yam, (2) it is difficult to solve the problem of rut ditch during the rainy summer period, (3) there is no special yam harvesting machinery
