Detailed Explanation of Key Technical Points for Spring Planting of Sweet Corn
Everyone likes to eat fresh sweet corn. It has a large market capacity, high yield, and good economic returns. From sowing to fresh ear harvest is about 90 days, and it does not affect the planting of hybrid rice. It is a good grain-and-cash cropping model with a yield of a thousand jin of grain and a thousand yuan per mu. Summarizing recent cultivation practice, to grow spring sweet corn well, the following points should be grasped: 1....

Detailed Explanation of Spring Fresh-Eating Sweet Corn Cultivation Techniques
Selecting good varieties: You can choose the sweet corn varieties Chaotian No. 3 and Chaotian 204, which were promoted and planted last year, or you can trial-plant and demonstrate new varieties such as Dongtian 206. These varieties have high yields, a medium growth period, a fresh grain sugar content of more than 16%, and good taste for fresh eating. Sow at the right time and cultivate strong seedlings. Generally, sowing begins around March 15 to 20, ...

Detailed Explanation of Key Cultivation Techniques for Spring Maize and Late Rice
1. Deep planting of milk-stage seedlings, dry management to promote root growth and preserve seedlings. The techniques of raising seedlings in fertilizer balls and soft trays must be implemented, and the technique of deep planting of milk-stage seedlings must be carried out well. According to research, transplanting milk-stage seedlings has the advantages of early vigor and strong seedlings, strong dry matter accumulation capacity, sturdy plants, well-developed root systems, large and numerous ears with heavy grains, and low empty-stalk rate; its early-maturing and high-yielding growth advantage is 6 days earlier than production cultivation, and the seedling recovery period...

Occurrence Patterns and Control Methods of Black-Streaked Dwarf Disease in Spring Corn
Black-streaked dwarf disease is a viral disease transmitted by the virus-carrying small brown planthopper (Laodelphax striatellus), with the seedling stage being the main susceptible period. Since the 1990s, with changes in planting structure, black-streaked dwarf disease in single-season rice and spring corn in Chun'an County has worsened year by year, especially since 2000, when rice black-streaked dwarf disease has occurred throughout the county,...

What are the spring lodging prevention measures for wheat? Explained clearly in one article
Lodging is one of the main factors affecting high and stable yields and good quality in wheat. Wheat lodging mainly occurs in high-yield wheat fields with ample fertilizer and water, excessive wheat growth, overly large populations, and dense, shaded field conditions. Early spring is the key period for preventing wheat lodging, and its comprehensive lodging prevention technical measures are: scientifically manage fertilizer and water. For high-yield wheat fields with a population of more than 650,000 plants per mu at the green-up stage, wait until the first internode of wheat has reached its final length (that is, late jointing stage), then apply topdressing and irrigation, applying 7.5-10 kg of urea per mu. This can reduce ineffective tillers, lower the length of basal internodes, promote thick and strong stems, and prevent lodging later, while also increasing grain number per spike and improving quality.

Detailed Explanation of Key Technical Points for Spring Cotton Sowing
Determine the density according to variety, soil fertility and planting method, and plant at a reasonable density to achieve full emergence from a single sowing. Generally, when a single spring cotton variety is planted, the density per mu is kept at around 3500 plants, with a row spacing of 1 m and a plant spacing of 19 cm; for semi-spring varieties, the density per mu is generally kept at around 4500 plants, with a row spacing of, and a plant spacing of 15 cm; for summer cotton varieties, ...

Spring cotton production technical guidance: how to manage the Yellow River basin cotton region
Raising seedlings and transplanting Simplified seedling raising and transplanting. First, choose a good seedling-raising site. It should be high-lying, sheltered from the wind and facing the sun, with convenient access to water and transportation. Second, prepare materials. Use seedling-raising substrate plus clean river sand to make a seedbed or fill plug trays, replacing nutritional pots, and prepare enough materials for 500 seedlings per sq m of seedbed. Third, sow at the right time...
