Key Technical Points for Winter Potato Cultivation with No-Till or Minimum-Till Rice Straw Mulching
I. No-till or minimum-till field preparation. 1. Selection of no-till or minimum-till fields. No-till or minimum-till potato cultivation is best carried out in sandy loam fields with convenient drainage and irrigation, loose soil, a pH value of 5.5-6, and good water and fertilizer retention. It is especially suitable for planting in sandy loam paddy fields with good drainage and irrigation conditions during the winter fallow period in our city. Fields prone to drought and water shortage and shallow, poor fields, heavy clay fields, low-lying fields, mountain pit fields, cold waterlogged fields, and rotten

Key Points of High-Yield Winter Cultivation Techniques for Potatoes
1. Site selection and land preparation. For winter-planted potatoes, choose sandy loam soil with convenient transportation, deep topsoil, good drainage and aeration, rich organic matter, sufficient water sources, convenient irrigation and drainage, slightly acidic, and with rice as the previous crop. Land preparation should involve deep plowing and fine harrowing, ensuring the loose soil layer reaches more than 8 cun; form ridges and beds, with double-row planting ridge surface width of 2.5-2.8 chi, furrow width of 7-8 cun, requiring fine and crumbly soil clods, with ridge surfaces and furrow bottoms level and straight. 2. Seed potato treatment and cutting. After purchasing seed potatoes, remove diseased, rotten, and mixed potatoes, spread out the good seed potatoes and spray with 200-fold formalin or 600-fold Daconil

Recommendations for the Occurrence and Control of Pests and Diseases in Winter Potatoes
In recent years, the potato planting area in our city has been continuously expanding, and various potato pests and diseases have been occurring in succession, seriously affecting potato yield and quality. It is currently the potato growing season. According to recent surveys conducted by our station and the Huidong station in Tieyong, Renshan and other places, the main pests and diseases occurring in winter potatoes in our city include: potato bacterial wilt, blackleg, late blight, viral diseases, as well as underground pests and aphids. All localities should strengthen surveys, and in particular, do a good job in controlling soil-borne diseases of potatoes. I. Occurrence of Pests and Diseases

Detailed Explanation of Key Points of Winter Potato Cultivation Techniques
I. Sow at the right time to seek advantages and avoid disadvantages. The best sowing time for winter potatoes is when the soil temperature at a depth of 10 cm reaches 7 or 8°C. Within the range not affected by frost, sow as early as possible. This allows harvesting before the arrival of high summer temperatures and helps obtain a higher yield. Late sowing leads to severe late blight in the later stage and poor storability. II. Select good varieties and promote sprouting to encourage seedlings. Potatoes are planted in different locations to help resist disease and achieve high yield. Choose varieties such as Zihuabai Kexin No. 3 and Kexin No. 1, which have high yields. Before sowing, sprouting must be carried out.

Growing potatoes in idle winter fields yields good returns
1. Choose good field plots and sow at the right time. Choose double-cropping rice areas below 100 m altitude, with little or no frost in winter and an average annual temperature above 19°C, requiring paddy fields with deep topsoil, loose texture, medium-to-upper fertility, and convenient drainage and irrigation; at the same time, arrange the sowing period reasonably. After the double late rice is harvested in mid-November, immediately plow deep and sun-bleach the soil, sow in early to mid-December, and harvest from late March to early April the following year. 2. Prepare the land finely and make deep furrows and high ridges. Potatoes grown in paddy fields in winter are most afraid of waterlogging, so fine land preparation should be advocated, with deep plowing and high-ridge cultivation, and planting

Detailed Explanation of Key Points of Potato Intercropping and Relay Cropping Techniques
Intercropping and relay cropping of potatoes with grain, cotton and vegetable crops can greatly improve the utilization of light energy and land, and increase the economic benefit per unit area. Test results from Zhangqiu City, Shandong Province show that cotton-potato relay cropping can yield more than 260 kg of lint cotton and more than 2,100 kg of potatoes per mu; spring potato - corn - autumn potato intercropping and relay cropping can yield 2,100 kg of spring potatoes, 590 kg of corn and 1,300 kg of autumn potatoes per mu. The net benefit of these two cultivation models can be 100 percent higher than that of monoculture cotton or corn.

Dragon Claw Jujube is a gnarled and vigorous plant for winter branch appreciation
Dragon Claw Jujube, also known as Dragon Whisker Jujube, Dragon Jujube, Dragon Wandering Jujube, and Bent Jujube, gets its name because its branches twist and coil in the shape of dragon claws. It is an ornamental variety with a uniquely shaped branch structure in the jujube family. Its tree form is graceful, with lush green leaves in summer, beautiful red fruits in autumn, and especially after leaf drop in winter, the twisted branches resemble a flock of dancing dragons, standing out uniquely among various ornamental flowering trees and shrubs. Dragon Claw Jujube can be planted in parks, plazas, courtyards or residential communities, and can also be grown in containers for appreciation or made into bonsai. Its rugged and vigorous form can also be used as auxiliary material for flower arrangements and floral art. Dragon Claw

Key Management Techniques for Jujube Orchards in Late Autumn and Early Winter (Part 3)
The third step is to apply a heavy base fertilizer. The most suitable time to apply base fertilizer is from after the jujube fruit harvest until before leaf fall, generally in early to mid-October. Generally, trees in the growth and fruiting stage are given 30-80 kg of organic fertilizer per tree, mixed with 0.2-0.4 kg of urea and 0.5-1.0 kg of superphosphate; large trees in full fruit stage are given 100-200 kg of organic fertilizer per tree, mixed with 0.4-0.8 kg of urea and 1.0-2.5 kg of superphosphate.

Winter control of psyllids in pear orchards leads to good pears in autumn
The pear psyllid is the most important pest on pear trees. It can damage pear leaves, causing blighted spots, weakening tree vigor, and reducing fruit quality and yield. It produces 4-5 generations per year. Adults are divided into winter and summer forms. Winter-form adults overwinter in the cracks of pear tree branches and trunks, with a few in weeds, fallen leaves, and soil. Integrated control should target their overwintering sites. 1. Orchard sanitation. Clear away fallen branches, fallen leaves, and weeds in and around the orchard, bury them deeply or burn them, to reduce the overwintering pear psyllid population. 2. Bark scraping. Spread plastic film on the tree tray
