Detailed Explanation of the Cotton and Potato Intercropping Cultivation Model
The cotton and potato intercropping model is applied on a relatively large area in the northern Jiangsu region. The symbiotic period of the two crops is not long, the mutual influence during the symbiotic period is small, and there is a complementary effect in fertilizer utilization. In the late growth stage of potatoes, the field has sufficient fertilizer and water, which is conducive to the seedling development of cotton, and can achieve high yields of both cotton and potatoes. Generally, the potato yield is 2000-2500 kg per mu, the cotton yield is 80-100 kg per mu, the output value per mu is 2500-3000 yuan, and the net income is 1500-2000 yuan. Generally, the bed width is about 3 m, and cotton is planted in wide and narrow rows

The modern potato industry technology system is being built by the Ministry of Agriculture.
It focuses on demonstrating and promoting advanced, applicable, efficient, high-quality and water-saving cultivation techniques for dryland potatoes, accelerating the integration and transformation of agricultural scientific and technological achievements, and using this as a marker to drive the technological upgrading and sustainable development of China's potato industry. On July 22-23, the Department of Science and Technology of the Ministry of Agriculture, together with the Department of Crop Production, held the "National On-site Observation Meeting on Water-Saving, Efficient and High-Quality Cultivation Techniques for Dryland Potatoes" in Ulanqab, Inner Mongolia. According to reports, the potato, used as both food, vegetable, feed and processing raw material, has now become the world's fourth largest food crop after rice, wheat and corn.

What is osthole? Introduction to the mode of action of botanical pesticides
Osthole - Osthole is the active ingredient extracted from the dried, mature fruit of Cnidium monnieri (cnidium fruit), a plant of the Apiaceae family; the formulation is 0.4% osthole emulsifiable concentrate. It acts mainly by contact toxicity, with stomach toxicity as a secondary effect, and has good control efficacy against cabbage caterpillars on cruciferous vegetables and tea geometrid moths on tea plants. For controlling cabbage caterpillars on cruciferous vegetables, the dosage is 80-120 ml of 0.4% emulsifiable concentrate per 667 sq m; for controlling tea geometrid moths on tea plants, the dosage is 100-120 ml of 0.4% emulsifiable concentrate. Generally, per 667 sq m use

The prospects for yellow catfish polyculture are good, and this farming model is worth paying attention to
Yellow catfish, also known as gayazi, huangga, angsi and so on, is an important economic fish in China's freshwater aquaculture. The flesh of yellow catfish is tender, nutritious and delicious, and market demand has continued to grow rapidly in recent years. Because the yield from natural waters and pond culture is very limited, it is difficult to meet the growing market demand, which has kept the market price of yellow catfish high for a long time. Polyculture of yellow catfish in ponds requires little investment and offers high returns, and the farming prospects are generally viewed favorably. Pond conditions: Ponds for polyculturing yellow catfish should be chosen with good water source conditions and no pollution

Integrated fish-and-goose farming model boosts farmers' income by 30 percent
Mixed farming of fish and geese is, for fishermen, a scientific farming model with "ten benefits and not a single drawback." This model makes full use of water surface and land resources, and under the same conditions increases economic returns by up to 30% compared with raising fish or geese alone, making it an effective new path to prosperity for fishermen. Advantages of integrated fish-and-goose farming: geese are fully automatic, energy-saving and highly efficient aerators for fish ponds. When fish and geese are raised together, farmers need not worry about oxygen depletion in the water caused by weather changes, because in low-pressure weather geese will rush to jump into the water, bathe and chase each other, churning up the water

Potato Intercropping Cultivation Models and Key Technical Points
To improve land utilization and increase farmers' income, several intercropping and relay-cropping models with potato as the main crop are introduced here, for the reference of farmer friends and grassroots leaders in adjusting the agricultural structure. 1. Potato-cotton. Potatoes are sprouted in late January and sown in mid-to-late February, using plastic film mulch cultivation. The varieties selected are virus-free potatoes Zheng Yin No. 5 and Zheng Yin No. 7, bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences; for cotton, the large-plant, disease-resistant Biao Za A1 is preferable. Potatoes are planted in double rows on high ridges, with wide rows of 8

What are the key cultivation points of the potato-rice-vegetable rotation model?
The potato--rice--vegetable model is mainly promoted in mid- to high-altitude areas. The key cultivation points are as follows: (1) For potatoes, choose late-maturing varieties with high resistance to late blight, such as Jizhangru No. 5. (2) For late rice, it is advisable to choose high-quality combinations such as Liangyou 2186 and D702 Youduoxi No. 1, so as to take advantage of the large day-night temperature difference in autumn in mid- to high-altitude areas and the good grain filling of rice. (3) In mid- to high-altitude areas, winter temperatures are relatively low, so for winter vegetables it is advisable to choose cold-tolerant types and cold-tolerant varieties.

Detailed Explanation of the Southern Pig-Biogas-Fruit Ecological Model and Supporting Technologies
"Pig----Biogas----Fruit" makes use of resources such as mountain land, farmland, water surfaces, and courtyards, adopting the "biogas digester, pigsty, and toilet" three-in-one project, centering on leading industries, and carrying out comprehensive utilization of the "three biogas products" (biogas, biogas residue, biogas slurry) according to local conditions, achieving efficient use of agricultural resources, ecological environment construction, improved agricultural product quality, and increased farmer income. The project's orchard (or vegetable plot, fish pond, etc.) area, pig breeding scale, and biogas digester volume must be reasonably combined. The model engineering technologies include pigsty construction, biogas digester engineering construction

Several High-Yield Potato Cultivation Models Introduced
In recent years, the Potato Association of Ziyang District, Yiyang City has actively explored high-yield potato cultivation models and carried out contiguous demonstration planting in Xiangpulun Township, Yingfengqiao Town, Changchun Town and other places, forming a complete high-yield cultivation technology system. Spring potato - double-cropping rice cultivation. For spring potato, early-maturing varieties such as "Dongnong 303" are selected, sown from mid-to-late December to early January of the following year, and harvested from late April to early May. For early rice, late-maturing varieties are selected, using sparse sowing for strong seedlings or two-stage seedling raising, and after the potato harvest in early May,

Detailed Explanation of a Reference Fertilization Model for High-Yield Rice
The soil-testing formula fertilization model for a rice yield of 450-550 kg per mu is as follows: (1) Total fertilizer amount and ratio The nitrogen, phosphorus and potassium ratio should be about 1:0.5:0.9, and the total amounts should be approximately: nitrogen 10-13 kg, phosphorus pentoxide 5-7 kg, potassium oxide 8-12 kg. (2) Fertilization plan 1. Basal fertilizer: (1) Organic fertilizer: generally for early rice, apply 1000-2000 kg of fresh green manure per mu, or 500-1000 kg of barnyard manure, or commercial organic
