Detailed Explanation of High-Efficiency Cultivation Techniques for Potatoes with Three-Layer Film Mulching
In early spring in the Lunan region, potatoes are cultivated with three-layer film mulching - a large arch shed with small arch sheds inside and plastic film covering the cultivation ridges. The harvest period is around late April, about 40 days earlier than open-field potatoes reaching market, with a price of up to 4 yuan per kilogram; generally, 667 sq m yields 2000-2500 kg of tubers, with an income of 8000-10000 yuan. The main cultivation techniques are introduced as follows: 1. Select good varieties. For three-layer film mulched potatoes, early-maturing varieties with a short dormancy period, early tuber formation and resistance to rot should be selected, such as Luyin No. 1, Jinshu No. 8 and Zaodabai, etc.

Detailed Explanation of High-Efficiency Double-Layer Mulch Cultivation Technology for Garlic
Qi Xinqiang, a garlic farmer in Qijiazhuang Village, Dingzhou City, Baoding, has grown mulched garlic for many years and, in the course of production, worked out a cultivation technique using double-layer plastic film mulch for garlic, achieving an earlier market launch for the garlic and relatively high yields, with a per-mu yield increase of more than 10%. It is worth the study and reference of vegetable growers in the major garlic-producing areas. The cultivation technique is introduced below: 1. Selection of excellent varieties. Select Shandong Guanxian garlic, an excellent garlic variety from Shandong Province and also an important export variety. Each garlic bulb has 7-8 cloves, the outer skin is slightly purplish-red, the skin is thin, the cloves are plump, the pungency is strong

How should the water layer be regulated at different growth stages of shallow-water lotus root?
The suitable water level for shallow-water lotus root is 10-20 cm, and the maximum water depth it can tolerate is 50 cm. In cultivation, the water layer must be well regulated according to the different growth stages of shallow-water lotus root. The general principle of water layer management for shallow-water lotus root is shallow at the front, deep in the middle, and shallow at the back. After planting the lotus root, when the standing leaves appear, maintain a shallow water layer of 4-7 cm to increase soil temperature and promote sprouting. As the stems and leaves grow vigorously, gradually deepen the water layer to 12-15 cm. After the terminal leaves appear, the plant begins to form lotus root, and the water layer is gradually lowered to a depth of 4-7 cm to promote lotus root formation.

Detailed Explanation of Multi-Layer Covered Seedling Cultivation Technology for Cucumbers in Spring Greenhouses
1. Do not arbitrarily change the light-receiving angle of the greenhouse. The angle of the solar greenhouse currently used for cucumber cultivation has been scientifically verified over a long period. Its north-south span, height, and rear slope angle should not be arbitrarily changed. 2. Do not apply concentrated fertilizer at transplanting. Various chemical fertilizers, especially nitrogen fertilizers, under humid and high-temperature conditions, will produce large amounts of...

Key Technical Points for Multi-Layer Covered Seedling Raising of Cucumbers in Spring Greenhouses
I. Greenhouse Structure. The best span for the greenhouse is 6-8 m. Put on the greenhouse film in early November. Set up a 1.5 m low tunnel inside the greenhouse and cover it with 3 m wide greenhouse film. At night, cover the low tunnel with a thick straw mat, and add a layer of old greenhouse film over the straw mat, which greatly enhances heat preservation. After seedling raising, cucumbers can still be planted in the greenhouse. II. Nutrient...
