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.

Detailed Explanation of the Characteristics and Main Cultivation Techniques of Brazilian Upland Rice
Brazilian upland rice LAPAR-9 is one of a batch of improved crop varieties that the Brazilian government presented to our country in 1992 during Premier Li Peng's attendance at the United Nations Conference on Environment and Development. Since 1993, our institute has planted it successively on hillside land, water-deficient fields, orchards and tea gardens in Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, Chongqing, Sichuan, Shaanxi, Shanxi, Zhejiang and **, with an average yield of 200-300 kg per mu; on plots with good fertilizer and water conditions, the yield can reach 400 kg per mu, and at its highest more than 500 kg per mu.

What pesticide gives the best control effect against older larvae of the rice leaf roller?
Chlorpyrifos and abamectin-monosultap are effective agents for controlling the rice leaf roller, but they must be applied during the 1st-2nd instar young larval stage (at this stage the rice leaf roller has not yet rolled leaves and caused damage, or has just begun rolling the leaf tips and causing damage), when the rice in the field has just begun to roll leaves. For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

What issues should be paid attention to in the management of single-season rice and other field crops
In the past week, the weather has continued to be hot with strong sunlight, field evaporation has been very high, and some rainfed fields have already experienced water shortage and drought. In the management of single-season rice and other field crops, attention should be paid to the following issues: 1. Spraying for disease and pest control should be done in the morning and evening, and sufficient water should be used. At present, it is the suitable period for controlling the fourth (2) generation leaf roller and rice planthopper of single-season rice. When selecting appropriate pesticides for control, the spraying time should preferably be before 8 a.m. or after 5 p.m., avoiding the high-temperature and strong-sunlight period as much as possible, and sufficient water should be used

Wuchang rice drinks fruit juice and takes calcium tablets to grow into ecological rice
Have you ever heard of a rice nutrient solution that people can drink? The fruit enzyme made by Liang Yingfen of Wuchang City, Heilongjiang Province, is drinkable by people. She used her homemade nutrient solution to replace rice foliar fertilizer, and the organic rice she produced was praised by experts for its high nutritional value. Liang Yingfen is a Korean ethnic farmer from Minle Township, Wuchang City. A rice blast disease in 2004 nearly wiped out all 6 mu of rice in her family. After many years of working with rice, Liang Yingfen realized that continuing to use chemical fertilizers and pesticides was very dangerous. The soil was getting poorer the more it was farmed, crop diseases and pests were increasing, and especially the residues of chemical

How to Return Rice Straw to the Field? A Detailed Guide to Five Practical Techniques
1. Short-cut rice straw incorporation by plowing technique. Cut the rice straw by hand or machine into lengths of 15-20 cm, and spread it evenly over the paddy field. Generally, the amount of dry rice straw spread per mu is 200-250 kg; if early rice straw is used for return, the amount spread per mu of main field is 1/2 or 2/3 of the total rice straw per mu. After the rice straw is spread, on the basis of the original fertilizer amount, apply an additional 8-12 kg of ammonium bicarbonate or 5-6 kg of urea per mu as base fertilizer; if it is a cold-waterlogged field, apply 15-25 kg of lime per mu in combination to accelerate the softening and rotting of the rice straw. The final

Correct Methods and Technical Key Points for Returning Rice Straw to the Field
1. Rice straw mulching in wheat fields. After wheat sowing is completed, use 250-300 kg of rice straw per mu, cut into 10-20 cm straw segments, and spread evenly over the field so that the straw does not form piles and the soil is not left exposed. 2. Rice straw mulching in rapeseed fields. When transplanting rapeseed, plant the seedlings according to the specified spacing into holes with sufficient basal fertilizer, cover with soil, and then evenly spread rice straw over the whole field at 300 kg/mu, so that the straw does not cover the holes (seedlings) and the soil is not left exposed, while also applying integrated chemical weed control and necessary field management measures. 3. Drainage and
