Intercropping Cultivation Techniques for Licorice in Land Returned from Farmland to Forest
Intercropping licorice in land returned from farmland to forest can both conserve soil and water and increase economic returns, achieving the goal of using the land to support the forest and the forest to support the land, and realizing a "win-win" for both the economy and ecology. Since 2002, Regiment 137 has conducted cultivation trials of intercropping licorice in land returned from farmland. After several years of experimentation and exploration, breakthrough progress has been made. 1. Land selection: Select sandy loam plots of land returned from farmland to forest with relatively low salinity and alkalinity, relatively few field weeds, and good drainage for intercropping licorice. The main tree species planted in the sowing area is wolfberry seedlings; the planting pattern is furrow planting

Intercropping insect-resistant cotton with potatoes: both crops can achieve high yields
In recent years, the model of intercropping potatoes with insect-resistant cotton has been welcomed by the people. According to surveys, this model not only enables cotton to achieve high yields (lint yield of 90-100 kg per mu), but also "freely" yields an extra 1500-2000 kg of potatoes per mu. The key cultivation techniques are as follows. I. Potatoes ① Seed selection and sprouting. It is advisable to choose early-maturing, short-stalked, high-yielding virus-free varieties, such as Holland No. 7, Jinyin No. 8, etc., using 80-90 kg of seed potatoes per mu. In mid-February, cut the seed potatoes into pieces (each kg cut into 40-50 pieces) and use a sunny cold frame or greenhouse

Common field planting patterns for intercropping cotton with potatoes
The cotton-potato intercropping pattern is widely used in northern Jiangsu; the two crops have a short symbiotic period, little mutual influence during that period, and a complementary effect in fertilizer use. The ample fertilizer and water in the field during the late growth stage of potatoes favor cotton seedling development, allowing a double high yield of both cotton and potatoes. Generally, potatoes yield 2000-2500 kg per mu and cotton yields 80-100 kg per mu, with an output value of 2500-3000 yuan per mu and a net income of 1500-2000 yuan. The bed is generally about 3 m wide, and cotton is planted in wide and narrow rows, with wide rows 150 cm apart and narrow rows

Cotton and lily intercropping planting pattern
Cotton and lily intercropping is a cotton-field intercropping pattern widely used in coastal and riverside dryland sandy loam areas. The two crops affect each other little and are mutually beneficial in fertilizer use, but note that lily cannot be continuously cropped and must be rotated to a different crop. This intercropping pattern generally has a bed width of about 3 m, with cotton planted in wide and narrow rows, the wide row spacing being 140 cm and the narrow row spacing 50 cm, with 4 rows of cotton per bed. In the wide cotton rows, 6 rows of lily are planted, with a row spacing of 20 cm and a plant spacing of 20-25 cm, at 5000-6000 plants per mu. Cotton is raised as seedlings and transplanted, planted separately on both sides of the bed,

Cultivation Methods and Technical Key Points for Intercropping Garlic in Cotton Fields
When garlic is intercropped in cotton fields, each mu can produce 93 kg of lint cotton and 1,300 kg of garlic, with a benefit of about 3,300 yuan per mu. 1. Cotton: Use insect-resistant hybrid cotton varieties such as Kemian No. 3 and Kemian No. 6. Before sowing, deeply plow the land 25 cm, and together with plowing, apply 3,000 kg of decomposed livestock and poultry manure and 60 kg of potassium sulfate compound fertilizer per mu. Broadcast 2-3 kg of 5% phoxim granules per mu to control underground pests. The suitable sowing period for cotton in Pizhou City is around April 3. Seize sunny days to raise seedlings in double-film nutritional pots. Prepare about 3,000 pots per mu of field. After watering the seedbed thoroughly, sow dry seeds, 1 seed per pot. About 0.35 kg of coated cotton seed is needed per mu of field. After full emergence, ventilate promptly to reduce humidity and control pests and diseases, and cultivate strong seedlings. Transplant around May 12 when cotton seedlings are at the 4-leaf stage, using equal-row spacing with a row spacing of 1.2 m and a plant spacing of 33 cm, planting about 1,700 plants per mu. In mid-to-late May, together with hilling, apply 15-20 kg of urea, 50 kg of superphosphate, and 20 kg of potassium chloride per mu. Around July 20, apply flower and boll fertilizer according to cotton growth, with 30 kg of urea and 15 kg of potassium chloride per mu. In early August, apply topdressing for boll development, with 7.5-10 kg of urea per mu. Pay attention to spraying trace element solutions such as boron fertilizer and monopotassium phosphate. Use mepiquat chloride for chemical regulation 4 times: 1-1.5 g per mu at the full bud stage, 2-2.5 g per mu at the early flowering stage, 3-4 g per mu at the full flowering stage, and 3-5 g per mu after topping. Top around August 6. Pay attention to controlling the third generation of cotton bollworm, cotton aphid, mirids, red spider mites, tobacco whitefly, and other pests. Pull up cotton stalks in mid-November.

Detailed Explanation of Key Techniques for Lily Intercropping and Relay Cropping
In the Taihu Lake region of southern China, lily production often uses intercropping and relay cropping to increase income per unit area. Practicing intercropping and relay cropping has some effects on lily growth, and bulb yield decreases somewhat, but the total income per unit area is higher than the returns from monocropped lilies. If the timing and management of intercropping and relay cropping are arranged properly, it is beneficial to lily growth and can also achieve high yields at the same time. Yixing lilies are propagated from daughter bulbs, require a large amount of seed, multiply only 2.5-3.5 times in one year, and the ground space is idle for a considerable period. Local experience in arranging intercropping and relay cropping

Field management of wheat-intercropped cotton must be followed up in time
1. Growth and development characteristics of wheat-intercropped cotton. For wheat-intercropped cotton, the cotton seedlings are weak after wheat harvest, grow and develop slowly, bud and flower late, are prone to excessive vegetative growth in the mid-season, and tend to mature late in the late season; moreover, this year the cotton seedling stage was affected by rainfall and low temperatures, and seedling diseases were relatively severe. Field management after wheat harvest must be based on the word "early" and vigorously grasp the word "quick" to promote rapid growth and development of the cotton seedlings so as to make up for insufficient growth during the seedling stage. 2. Quickly destroy the wheat stubble and loosen the soil
