  • Detailed Explanation of High-Efficiency Supporting Production Technology for Oil Pumpkin and Rice (Part 2)

    IV. Supporting Watermelon Interplanting Technology 1. Fertilization and transplanting. Before interplanting watermelon, apply 1800-2400 kg of organic fertilizer per 667 sq m, and 50 kg of watermelon-specific fertilizer, applied into holes before planting. Interplanting is carried out in late April. After transplanting, promptly water with a 0.3% urea solution to settle the roots, so as to improve the survival rate of the watermelon seedlings. Pay special attention that the concentration of the root-settling manure water must not be too high, to prevent damage to the seedlings. 2. Vine pruning and fruit setting. For vine pruning, adopt the two-vine or three-vine system, that is, 1 main vine with 1-2 side vines, and

  • Introduction to Specialty Rice Varieties: Getting to Know Common Types of Specialty Rice

    In recent years, the Department of Agronomy at South China Agricultural University has bred several specialty rice varieties, mainly including fragrant rice, fragrant black rice, red zhan rice and others. Their varietal characteristics and key cultivation points are briefly introduced as follows: 1. Wanxianxiangzhan No. 1: Wanxianxiangzhan is a variety bred by crossing Wanlixiang with Jingxian 89, and is an early-season, medium-maturity, high-quality fragrant rice. When planted in the Guangzhou area in the early season, the whole growth period is about 125 days, plant height is 90 cm, plant type is moderately compact and spreading, tillering ability is medium, each panicle has 150-200 grains, it has a certain fragrance, good eating quality, and good late-stage ripening color.

  • How good is the Super Large Grain King rice variety?

    Zhezao 15 is a super-high-yield early indica rice new line developed by mutagenesis treatment using the super-high-yield genetic advantage of "Zhe 18500". After multi-point trial planting as early rice by the Zhejiang Academy of Agricultural Sciences, the yield generally reaches more than 600 kg per 667 sq m (1 mu). The characteristics and advantages of Zhezao 15 are introduced as follows: 1. Extremely strong tillering ability, low seed requirement. The effective tillers per plant can reach 12-15, and 1 kg of seed per 667 sq m of field is sufficient. 2. Cold tolerance at the seedling stage, disease resistance at the later stage. Strong cold tolerance at the seedling stage, so sowing can be appropriately advanced

  • 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 when growing rice with well water is crucial. The specific technical measures are: 1. Set up a solar warming pond to raise the water temperature. Adding a solar warming pond is an effective measure to raise the water temperature when growing rice with well water. The area of the solar warming pond should be based on actual conditions and adapted to local circumstances. Generally, the area of the solar warming pond should be 1500-2000 sq m, preferably reaching about 1/20 of the irrigation area of the pump. According to experimental research, 2

  • How to control rice thrips? Control methods and technical key points

    (1) Life habits: The rice thrips is very small, with adults only 1 mm to 1.5 mm long, dark brown. In winter, adults overwinter in gramineous weeds and on wheat crops. During the seedling-raising period of the following year, when the seedlings grow to 2 to 3 leaves, they fly into the seedling fields to lay eggs and reproduce. The insect body is small and very active, able to fly and jump. Adults are attracted to green, and after the seedlings are transplanted, they enter the tillering stage when food is abundant, which facilitates massive egg-laying and reproduction, damaging the heart leaves and young tender tissues. In the early stage of leaf damage, small white spots appear, and the upper part of the leaf tip curls inward, causing

  • Introduction to Jiahua No. 1, a new conventional late japonica rice variety

    Jiahua No. 1 is a medium-maturity late japonica rice variety newly bred by the Jiaxing Academy of Agricultural Sciences in Zhejiang Province. It passed the approval of the Zhejiang Provincial Crop Variety Approval Committee in April 2004 and is suitable for cultivation as late japonica rice in northern Zhejiang and ecologically similar areas. In the Jiaxing single-crop late japonica rice regional trials in 2001 and 2002, the average yields per mu were 582.4 kg and 589.6 kg respectively, and the average whole growth period over the two years was 158 days; in the 2003 Jiaxing production trial, the average yield per mu was 523.9 kg. Jiahua No. 1 is

  • Occurrence and Control Methods of Rice Dwarf Disease in Japonica Rice

    I. Damage Symptoms The rice plant becomes stunted, with increased tillering, dark green leaves, and transparent yellowish-white dashed line streaks on young leaves and leaf sheaths. When the disease occurs at the seedling stage, tillering is reduced and the plant cannot head; when it occurs after booting, yellowish-white streaks appear only on the flag leaf or other leaf sheaths, and late-onset plants mostly produce neck-enclosed heads, small heads, many empty and shriveled grains, and a low seed-setting rate. II. Preventive Measures Once japonica rice contracts dwarf disease, it is very difficult to cure, so comprehensive preventive measures should be actively adopted. 1. Select disease-resistant

  • 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
