Detailed Explanation and Application of the New Muskmelon-Rice Multiple Cropping Technique
I. First Crop Muskmelon 1. Seed selection and land preparation: Choose high-yield, high-quality muskmelon varieties with a growing period of about 90 days, such as Chaozhao Tangwang and Hongchengcui No. 1. Before the ground freezes the previous year, plow the paddy field well, harrow, press and form ridges with a ridge spacing of 50-60 cm, and press firmly to preserve soil moisture. Along with land preparation, apply 5000 kg of high-quality farmyard manure per mu. 2. Seedling raising and transplanting: Soak seeds to promote germination in late February, raise seedlings in a greenhouse in late February to early March. You may use seedbed seedling raising followed by pricking out into seedling bowls, or directly raise seedlings in seedling bowls. For planting melons in the main field, transplant the melon seedlings into the main field before April 15.

Water-seeded direct-seeded rice has many advantages; what exactly are they?
Depending on the soil moisture conditions at the time of land preparation and the method of land preparation and sowing, direct-seeded rice can be divided into dry direct seeding and water direct seeding. Dry direct seeding can further be divided into methods such as sowing on stubble first followed by shallow rotary tillage, and rotary tillage first followed by sowing. The land preparation and sowing procedure for water direct seeding is roughly as follows: after applying base fertilizer, add water and rotary tillage, open furrows, level the field with water, then sow and press the seeds into the soil. Compared with dry direct-seeded rice, water direct seeding has the following advantages. First, more seedlings emerge and emergence is uniform, which is conducive to cultivating strong seedlings. In water direct-seeded fields, the bed surface is level, and there is mud slurry on top; after pressing the seeds into the soil, no seeds are left exposed, emergence is fast and

Safety Precautions for Wheat and Rice Threshing
Nowadays, combine harvesters are used for wheat and rice harvesting, threshing as they reap and storing the grain in time, but many farmers still use swathers and sickles to harvest, requiring on-site threshing, which poses some safety hazards worth noting. To ensure safe production, the following points should be mastered: 1. Preparations should be thorough. The thresher must be inspected by the agricultural machinery safety supervision department, and only after passing inspection can it be put into operation. Operators must undergo safety training and understand operating techniques and safety knowledge. Before working, a trial run should be conducted first; only after everything is normal

Practical methods for raising water temperature when growing rice with well water
The biggest drawback of growing rice with well water is the low water temperature, which affects the good growth and development of rice, leading to reduced yield and poor quality. Therefore, raising the water temperature for rice grown with well water is crucial. Specific technical measures: 1. Set up a sunning pond to raise the water temperature. Adding a sunning pond is an effective measure for raising the water temperature of rice grown with well water. The area of the sunning pond should be based on actual conditions and adapted to local circumstances. Generally, the area of the sunning pond is 1500-2000 sq m, and it is appropriate for it to reach about 1/20 of the irrigation area of the pump. According to experimental research, a 2000 sq m sunning

Which insecticide is effective for controlling the rice stem maggot?
The rice stem maggot has broken out and caused disasters in most rice-growing areas in China in recent years, making it a serious pest. At present, an insecticide for controlling pests such as the rice stem maggot has been successfully invented. The purpose of this invention is to provide a highly effective and low-toxicity insecticide specifically for controlling the rice stem maggot pest. The insecticide of this invention is prepared by mixing two agents, fipronil and imidacloprid, in a weight ratio of (1:0.1) to (0.1:1), and can be made into various formulations such as seed coating agents, seed dressing agents, suspension concentrates, powders, and emulsifiable concentrates. The advantages are: its insecticidal effect on the rice stem maggot

Rice seedlings turning yellow, leaves curling, leaf-rolling: what to do? A detailed guide to prevention and control
There are many causes of the rice leaf-rolling phenomenon, and the most common one is the rice leaf roller (Cnaphalocrocis medinalis). Damage characteristics: the larvae bind silk to roll rice leaves lengthwise into larval cases, and the larvae hide inside and feed on the mesophyll, leaving only the epidermis, forming white streaks, which reduces the 1000-grain weight of rice, increases empty grains, and causes yield loss. Control agents: 1. Select rice varieties resistant to (or tolerant of) the pest, fertilize reasonably, so that the rice grows and develops vigorously, and prevent excessive early growth and excessive tillering as well as late-season stay-green and delayed maturity. Manage water scientifically, adjust the drainage (field-drying) time appropriately, and reduce field humidity during the larval hatching period
