Problems solved by technology

[0009] In order to solve the problems of low economic value of crop species in the traditional "wheat/corn/sweet potato" model in the dry land of the Sichuan hilly area, labor-intensive, continuous cropping and annual yield, output value and low net income, the present invention is based on the ecological conditions of the dry land in the Sichuan hilly area.

Example Embodiment

[0048] Example 1

[0049] 1) Select spring sweet potato varieties

[0050] Choose the fresh sweet potato variety with extra early maturity and good taste, virus-free seed potato Longshu No.9.

[0051] 2) Integrate two kinds of seedlings for early spring sweet potato seedlings

[0052] Electric heating hotbed nursery: In early and mid-February, a geothermal line was laid in the greenhouse to build a geothermal seedbed, and the length of the nursery compartment was determined according to the length of the electric heating line. The geothermal line was evenly covered with soil and connected with an electric temperature controller to accurately control the temperature of the seedbed and the sweet potato to emerge Control the temperature of the seedbed at 25°C before and 25-28°C after emergence; select healthy and disease-free seed potatoes of uniform size, and arrange the seeds side by side, with the head and the tail connected. Water the seedling bed in time according to the soil moist...

Example Embodiment

[0062] Example 2

[0063] Except that Nanshu 88 was used as seed potatoes, the seedling raising method adopted electric heating hotbed to raise seedlings. The harvest was in mid-August of the current year, autumn potatoes were sown in the second half of the month, and the autumn potatoes were harvested in mid-December of the same year. Others were the same as Example 1. The measurement results As shown in Table 1.

Example Embodiment

[0064] Example 3

[0065] In addition to the selection of sweet potatoes as seed potatoes and the local three-layer film mulching method for seedlings, the harvest is harvested in mid-to-late September of the year, winter broad beans are sown in the first ten days of the following month after harvest, and winter broad beans are harvested in March of the following year. Example 1 is the same, and the measurement results are shown in Table 1.

Abstract

The invention discloses a method for staged harvest and whole-year production of early-spring sweet potatoes and relates to the field of agricultural cultivation. The method comprises the steps that an early-maturing and early-tuberization fresh detoxicated sweet potato variety with good stress resistance and a good taste is selected as seed potatoes; the seed potatoes are subjected to seedling growing, and when seed potato seedlings grow to the height of 20-25 cm, the parts on the ground are cut off to serve as seed potato seedlings for use; the seed potato seedlings are transplanted to a treated field for field planting, and root dipping is carried out on the seed potato seedlings before field planting; according to the harvest time of the sweet potatoes, different planting patterns are selected. According to the method, a novel dry land whole-year two-maturation efficient planting pattern with the key technology for early-cultivation high yield and staged harvest of the early-spring sweet potatoes serving as the core is constructed, the method is suitable for the ecological conditions of dry land in the hilly area of Sichuan and the existing planting technology, and the output value per mu of the dry land in the hilly area of Sichuan and net income of farmers are increased.

Description

Technical field [0001] The invention relates to the technical field of agricultural cultivation, and constructs a new type of double-cropping and high-efficiency planting mode in dry land, in particular to a production method for sweet potato early planting and harvesting in stages. Background technique [0002] Sweet potatoes, commonly known as sweet potatoes, sweet potatoes, etc., are rich in protein, starch, pectin, cellulose, amino acids, vitamins and a variety of minerals. They are known as "longevity foods". With the improvement of people's living standards, the health effects of sweet potatoes become more important. It has become more and more popular, and its planting benefits have gradually become prominent. [0003] China is the world's largest producer of sweet potatoes. Sichuan is one of the main sweet potato producing areas in China. As one of the main dryland crops in Sichuan, sweet potato has the highest potential for increasing production, income and processing afte...
