How to carry out chemical weed control in rice fields
I. Chemical weed control in seedling fields. 1. Fertile-bed dry-raised seedling beds. Fertile-bed dry-raised seedling beds have many weeds and great damage, so in control it is necessary to grasp the appropriate timing and comprehensively use 42% Xinye emulsifiable concentrate spray, and cover with film half an hour after spraying. For missed plots, after the three-leaf stage of the seedlings, water the bed surface fully,

Detailed Explanation of Key Points for Early-Stage Cultivation Management of Rice in Paddy Fields
As the saying goes, "three parts planting, seven parts management." After rice transplanting, it enters the paddy field management stage, and whether management techniques are in place has a great impact on per-unit yield. The core of early-stage cultivation management in paddy fields is "applying tillering fertilizer heavily and early." This can promote early and rapid growth of seedlings, ensure early formation of effective tillers, and lay the foundation for high yield.

Control Methods for the Dark Black Chafer in Peanut Fields
The dark black chafer is the dominant population harming peanuts in the Xinyi area, and its larvae (white grubs) not only severely damage peanut pods, but also feed on crop roots in soybean, corn, sweet potato, Chinese medicinal herb, flower and nursery stock fields. In production, corresponding measures should be taken during the adult and larval stages according to the occurrence

Five precautions for using herbicides in summer corn fields
The summer corn growing season coincides with high temperature and high humidity, and weeds in the field grow rapidly. In addition, with more rainfall, manual and mechanical weed control is relatively difficult and labor-intensive, so chemical weed control in corn fields is increasingly accepted and widely used by farmers. There are many types of corn herbicides with high application technical requirements

What are the control methods for wheat powdery mildew?
In recent years, with the improvement of fertilizer and water conditions in wheat fields and the increase in plant density in high-yield fields, wheat powdery mildew has become increasingly severe year by year. After the powdery mildew pathogen parasitizes wheat, the plant's respiration increases, transpiration intensity rises, and photosynthetic efficiency decreases, seriously affecting the normal

Experience in corn cultivation with plastic film mulching, suitable for corn fields in mountainous areas
In response to the relatively severe drought in Taiyi Township, Dali City since last year, adopting plastic film mulching cultivation is an effective way to ensure drought resistance, seedling survival and increased income for corn. Corn plastic film mulching has the following effects: (1) Temperature increase: daily temperature increases by 3.9°C at the seedling stage, 3.3°C at the jointing stage, and at the tasseling stage daily

Weed Control Methods in Schisandra Planting Fields
1. The survey results of weed species in Schisandra fields show that the weeds causing serious damage in Schisandra fields include barnyardgrass, crabgrass, amaranth, lambsquarters, field horsetail, foxtail, and shortawn foxtail, among which crabgrass, Asiatic dayflower, and lambsquarters cause particularly severe damage. 2. Conventional control of weeds in Schisandra orchards

Field Preparation Experience Before Sowing Dahurian Angelica
Dahurian angelica prefers warmth and moisture with plenty of sunlight; it fears high temperatures, can tolerate cold, and has fairly strong adaptability. Dahurian angelica is not strict about the preceding crop, and even a continuous cropping field where Dahurian angelica previously grew well can be selected. It is best to choose level terrain, plenty of sunlight, a deep tillage layer, and loose, fertile, well-drained sandy loam soil.

Key Cultivation and Management Techniques for Direct Seeding of Snake Gourd in Open Fields
Snake gourd is an annual climbing vine; the stem is slender, much branched, with longitudinal ridges and grooves, covered with short pubescence and sparsely with long hirsute hairs. The snake gourd has a well-developed root system with many lateral roots and readily produces adventitious roots. The vines are slender and long, reaching 5-8 m in length. The stem is five-angled and green, with strong branching ability.
