Key Points of No-Till Potato Cultivation Technology and Detailed Planting Methods
1 Application situation: This technology is mainly applied on 5000 mu of land in Enshi Prefecture in western Hubei, Zhijiang, Xiangfan City and the suburban areas near Wuhan City, saving about 50 yuan per mu in tillage and land preparation costs. Fresh potatoes are brought to market early in April to May, and the price can increase by more than 50%. 2 Key technical parameters 2.1 Choose middle-season rice fields near suburban areas. After the rice harvest, uniformly spray 200-250 ml of Gramoxone per mu onto the rice stubble and field weeds. After 24 hours, fertilizer can be applied and furrows opened to form beds. 2.2 Choose early-maturing potato

Identification and Control Methods for the Potato Ladybird Beetle
The potato ladybird beetle (Henosepilachna vigintioctomaculata Motschulsky) belongs to the order Coleoptera, family Coccinellidae. It is widely distributed in northern China. It mainly damages potatoes, eggplants, Chinese cabbage, rapeseed, as well as beans, cucurbits and so on. [Field identification] Both adults and larvae feed on leaves, gnawing the epidermis and mesophyll on one side, creating many net-like pits. The adult is about 8 mm long and hemispherical. The body dorsum and elytra are yellowish-brown; the center of the pronotum

Causes and Control Methods of Potato Green Skin Disorder
[Disease Diagnosis] It mainly occurs on tubers in the late growth stage or during storage. In the field, after some tubers arch out of the soil surface and are exposed to sunlight, the surface tissue turns from yellow to green. The area of greening varies depending on the size of the exposed area. The green tissue can extend into the interior of the tuber and is often accompanied by purple pigment deposition. During storage, when tubers are exposed to natural light, the surface also turns green, sometimes even affecting deep tissues. Usually this greening will not recover by returning the tubers to dark storage. [Cause] This disease is physiological

Detailed explanation of potato crispy candy slice processing technology, master all steps and methods
1. Selecting potatoes and slicing: Choose fresh potatoes weighing 50-100g with no pests or diseases, wash the soil off the skin, then place them in a 20% alkaline solution and stir constantly with a wooden stick to peel them. After all the skin has come off, scoop them out, rinse once, and drain for later use. For slicing, cut into diamond-shaped or triangular thin slices 1-2mm thick as needed; after cutting, immediately soak them in clean water to prevent the starch on the surface from discoloring. 2. Boiling and drying: Scoop out the cut slices soaked in water and put them into boiling water to cook. When they are 80% cooked, immediately turn off the heat and dry them. In this step, you must master

Causes of Secondary Growth in Potatoes and Control Methods
Nilka County has a narrow and long terrain with a cool climate, suitable for the growth of cold-loving crops. Potatoes have always been the dominant main crop in the area. Through years of in-depth investigation and research, technicians have identified the causes of secondary growth in potatoes and the corresponding solutions. I. Secondary growth in potatoes In early August 2003, in Village 5 of Nilka Town, 1.3 hectares of potatoes sown in late April had tubers that had swollen to the size of eggs, the buds on the new tubers sprouted, and small tubers the size of a thumb grew out, while the new tubers grew and aged, no longer continuing to expand.

Symptom Identification and Prevention Methods for Potato Cold Injury
During plant growth or during tuber storage, if the air temperature or soil temperature is too low (above freezing), the plant will suffer cold injury. The degree of cold injury varies with the temperature. 1. Leaf symptoms At the seedling stage, after the plant suffers freezing injury, the leaves quickly wilt and collapse. When the temperature becomes warmer, the affected parts become water-soaked and turn brown after dying. However, if the plant suffers only cold injury, the above symptoms will not appear. Cold injury occurs at the seedling stage in early spring. The symptoms appear at the top of the seedlings, showing light yellow to light brown at the base of the young leaves. When

Pre-storage Treatment of Potatoes and Several Practical Storage Methods Explained
1. Pre-storage treatment Pretreating the tubers before storage can inhibit potato sprouting and plays a very good role in ensuring storage results. (1) Sun-drying After harvesting, potato tubers can be spread out in the field to dry briefly, releasing some moisture to facilitate storage and transport. Generally, sun-drying for 4h can significantly reduce the incidence of disease during storage. If sun-drying lasts too long, the tubers will lose water and wilt, which is unfavorable for storage. (2) Pre-storage Potatoes harvested in summer coincide with the hot season; after harvest, the potato tubers should be piled in a cool, ventilated room, cellar or shade shed for pre-storage. For

Control Methods for Major Underground Pests of Potatoes
I. Major Pests 1. Mole cricket, also called lala cricket or earth dog. Both the adults (with fully developed wings) and nymphs (with incompletely developed wings) of the mole cricket cause damage to potatoes. It uses its mouthparts and large front claws (forelegs) to tear the underground stems or roots of potatoes into a tangled mass, causing the above-ground parts to wilt or die. It sometimes also bites the seed pieces, preventing the buds from growing and causing gaps in the stand. It tunnels through the soil, separating young roots from the soil and exposing them to air, causing water loss that affects seedling growth and can even kill the plants. In autumn, it bites the tubers, creating holes in them or making them

Symptoms and Control Methods of Potato Black Heart
[Disease Diagnosis] Mainly the tuber storage organ is affected. In the central part of the tuber, irregular patterns of black to blue-black form, developing from a spot to a patch into black heart. As it develops severely, the entire tuber can become discolored. The affected black heart area has a clearly defined edge. In the later stage, the black heart tissue gradually hardens. At room temperature, the black heart area can soften and turn ink-black. Different tubers vary greatly in their reaction to black heart. [Cause] This is a physiological disease caused by insufficient oxygen supply to the internal tissues of the tuber, leading to respiratory suffocation.
