Description
Technical Field
The invention belongs to the technical field of crop cultivation, and particularly relates to a cultivation method for effectively reducing the hydrocyanic acid content of cassava root tubers.
Background
Cassava, a genus cassava of the family euphorbiaceae, is the third potato crop in the world and is also the most important food crop in developing countries. However, cassava is a typical cyanogenic plant, cyanogenic glucoside is an endogenous toxic and harmful component in the cassava, so that the eating or processing quality of the cassava is limited, and the development of the cassava eating industry is influenced. Therefore, cyanogenic glucoside is one of the most key safety indexes of cassava products. Risk assessment of the Joint Experts Committee for Food Additives (JECFA) shows that the chronic risk of food safety of cyanogenic glycosides mainly originates from cassava, and effective measures need to be taken to reduce the content of cyanogenic glycosides in cassava.
At present, the means for reducing the cyanogenic glucoside content of cassava mainly comprise: (1) selecting and breeding a cyanide-free cassava variety; (2) controlling biosynthesis of cassava cyanogenic glucoside or accelerating catabolism of cassava cyanogenic glucoside from a molecular level through a genetic engineering technology; (3) a treatment for removing cyanogen by working. Because the cassava varieties generally have potential hydrocyanic acid content, the cassava varieties with low toxicity are relatively difficult to breed by the traditional breeding method; decyanation by a genetic engineering technology has high efficiency and small nutrient loss, but potential safety hazards exist in transgenosis; the decyanation of the processing means needs a relatively complicated process.
Therefore, if the cyanogenic glucoside content of cassava can be regulated and controlled by farming and cultivation measures, great economic and social benefits can be generated.
Disclosure of Invention
The invention aims to solve the technical problems and provides a cultivation method for effectively reducing the hydrocyanic acid content of cassava block roots.
The technical scheme of the invention is as follows:

(3) sowing: obliquely inserting cassava seed stems into the ridge surface;
other management is performed as usual.
Further, in the step (1), the ridge farming is performed as: the ridge smashing depth is 30-40cm, the ground ridge surface is trapezoidal, the ridge width at the top is 50cm, the ridge width at the bottom is 70cm, and the ridge distance is 100 cm.
Further, in the step (2), N, P in the nitrogen, phosphorus and potassium fertilizer2O5、K20 is 0 to 2.51kg/70m2、0.21～0.62kg/70m2、0.42～1.31kg/70m2。
Further, in the step (2), N, P in the nitrogen, phosphorus and potassium fertilizer2O5、K2The application ratio of 0 is 0: 1: 2, N, P2O5、K20 is 0kg/70m2、0.62kg/70m2、1.31kg/70m2。
Further, in the step (2), N, P in the nitrogen, phosphorus and potassium fertilizer2O5、K2The application ratio of 0 is 4: 1: 2, N, P2O5、K20 is 0.83kg/70m2、0.21kg/70m2、0.42kg/70m2。
Further, in the step (2), N, P in the nitrogen, phosphorus and potassium fertilizer2O5、K2The application ratio of 0 is 4: 1: 2, N, P2O5、K20 is applied in an amount of 1.66kg/70m, respectively2、0.42kg/70m2、0.84kg/70m2。
Further, in the step (3), the sowing time is 3 Laetia.
Further, in the step (4), the row spacing of the sowed plants is 1m × 1 m.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
the cassava ridge smashing cultivation method disclosed by the invention utilizes the special spiral drill head of the ridge smashing machine to vertically dig into the soil (30-40cm), and the tractor pulls the soil to move forward, so that the operation procedures of plowing, raking, beating and the like required by conventional cultivation can be completed at one time. The core of ridge smashing cultivation is that soil of a whole plough layer is uniformly smashed, and upper and lower soil layers are kept to be not disordered; compared with the traditional cultivation, the method has the advantages that the thickness of the soil plough layer and the physical growth space of crop roots are obviously improved, the utilization rate of water and nutrient resources is greatly improved, the factors such as water, fertilizer, gas and heat of the plough layer soil are coordinated, and a good soil growth environment is provided for the growth of cassava crops.
Tests prove that the powder ridge culture can not only increase the yield of the cassava, but also greatly reduce the hydrocyanic acid content in the cassava root tuber, and the hydrocyanic acid content is in a decreasing mode along with the reduction of the nitrogen concentration.
In tests, the inventor also finds that when the nitrogen fertilizer is applied in a reducing way by 34 percent and 67 percent (other fertilizers are not used for replacing the chemical fertilizers applied in the reducing way), the yield which is equivalent to the normal fertilization in the conventional farming is still obtained, and the content of the hydrocyanic acid in the root tuber is respectively reduced by 332.00 percent and 133.12 percent compared with the control, so that the economic benefit is better.
