Straw covering and no-tillage cultivation method of potatoes

Abstract

The invention relates to the field of potato cultivation, in particular to a straw covering and no-tillage cultivation method of potatoes. The method comprises the following steps of (1) selecting a no-tillage paddy field as a potato planting field, and ditching the field and bedding; (2) selecting seed potatoes, sterilizing the seed potatoes, cutting the seed potatoes into blocks, dressing seed and performing bud forcing treatment; (3) during seeding, placing potato bud eyes downwards or laterally to be closed to the ground, placing the potato buds on dry bedding surfaces, covering the bedding surfaces with straws, wherein the thickness of the straw layer is 8 to 10cm, and uniformly covering the bedding surfaces to the sides of the field; (4) applying a high-quality decaying manure or compost nearby the seed potatoes; (5) performing field management, after seed potato seedlings are completely grown, applying thin human fecaluria or biogas slurry to the seed potatoes, and during a growing period, properly adding a fertilizer to the seedlings according to the status of the seedlings to promote growth, or spraying paclobutrazol to control the seedlings, keeping the field wet, and paying attention to prevention and control of diseases and insects; (6) harvesting at proper time. The traditional potato seeding method is changed into a potato placing method, the traditional potato digging method is changed into a potato picking method, potato blocks are not damaged, and the potatoes are fresh and tender in color and good in commodity.

Description

technical field [0001] The invention relates to the field of potato cultivation, in particular to a potato straw-covered no-tillage cultivation method. Background technique [0002] Potatoes are also called ground eggs, potatoes, yams, yam eggs, etc. Potato tubers contain about 2% protein, and the protein content in dried potatoes is 8% to 9%. The nutritional value of potato protein is very high, and its quality is equivalent to that of eggs. It is easy to digest and absorb, and it is better than the protein of other crops. Moreover, potato protein contains 18 kinds of amino acids, including various essential amino acids that cannot be synthesized by the human body. Potatoes are highly evaluated for their nutritional value, and their tubers contain high-grade protein and essential amino acids lysine, tryptophan, histidine, arginine, phenylalanine, valine, leucine, and isoleucine The presence of amino acid and methionine are inseparable. [0003] Potato has short growth c...

Problems solved by technology

The disadvantage of this cultivation method is that the potatoes form tubers in the soil, and when the tubers expand, they are squeezed by the soil, which is not conducive to the expansion of the tubers. In the case of non-sandy loam, the resistance they receive is greater. Generally, the tubers are relatively small, large and medium-sized. The potato rate is low, and the planting method is complicated to operate, labor-intensive, and labor-intensive
