Rice Transplanting Drought Cultivation Technique

Rice Transplanting Drought Cultivation Technique

The "Yueyu 302" upland rice seedling inherited the advantages of the original rice dry farming technique, solved the problems of low yield and poor quality of the previous rice dry farming, accumulated rich experience for the development of water-saving green agriculture, and was well received by the general public. Farmer's welcome. It has been planted in large areas in Jilin, Liaoning, Heilongjiang, and Inner Mongolia, and has achieved good economic and social benefits. The technique of transplanting rice with dry cultivation is high, but it is not difficult to operate it. If it can be done strictly according to technical requirements, it will have a bumper harvest. The adaptability of the new dry-cultivated rice cultivars for transplanting has been proved by experiments. It can be planted in dry-land areas, small-scale rice paddies, low-lying lands, and severely water-poor rice growing areas. In order to achieve high yield and stable production, the following points should be noted in the selection and use of cultivated land: Choose a non-heavy clay ground with flat terrain, high groundwater level, close proximity to water sources, and no water leakage. Uneven land can be planted if it has watering conditions. 2. To select lands with relatively fertile land, it is imperative to apply more manure. 3. To select a mild alkali with a low salt content and a soil pH of 8 or less. 4. If Daejeon destroys crops, it is better to use corn, sorghum, and soybeans. 5. When the original Daotian block was planted, the paddy field should be leveled in order to expand the land use area and facilitate large-scale cultivation and management. The land preparation and fertilization methods for transplanting rice in dry land are basically the same as those for land treatment. During the site preparation, the last year's debris will be crushed and ridged, and the ridge spacing will be 55cm-60cm; 5000 kg of farmyard manure will be applied per acre, 20 kg of nitrogen, phosphorus and potassium ternary compound fertilizer, 10 kg of urea, and biomass. Potash 10 kg, sulfur zinc 2 kg. The method of application is to mix the various fertilizers uniformly, apply them to the ridge bottom, and suppress the ridges to prepare for transplanting. For rice transplanted with drought-induced seed, three varieties of "Education 302, 304, and 3" cultivated by the Yuliang Agricultural Technology Research Institute of Shuangliao City can be selected. Among them, No. 302 varieties have obvious advantages, and their characteristics are as follows: The seeds have strong buds, strong seedlings, and well-developed root systems, generally ranging from 40 cm to 50 cm, and ridges up to 80 cm. The growth period is 142 days. 2. Salt-tolerant, disease-resistant, drought-resistant, low-temperature resistant, live-bar mature, stem tough and not lodging, plant height about 90 cm. 3. Strong delivery and effective delivery rate. Generally, the number of panicles per acre cultivated in Xiaoping can reach 350,000 spikes, 18 cm to 22 cm in length, and 90 to 110 grains per panicle. The seed setting rate is 95%, and the grain weight is 28 grams. 4. The variety can be made of water, but it can also be cultivated without water. The output is generally 8000 kg per hectare, and the maximum can reach 10000 kg. The rice produced has a transparent appearance, good taste and strong market competitiveness. The earliest deadline for transplanting dryland rice sowing was 5 days and the average temperature reached 7°C. Jilin Province sowed seedlings between April 5 and April 10. In order to prolong the growth period of the dry season, the time for sowing and raising seedlings should be sooner rather than later. The transplanting time is the same as the time of planting rice, generally between May 20-30, and care should be taken to avoid frost. There are two types of farming methods for transplanting dry crops of rice, one is water-saving cultivation of small wells, and the Other is cultivation of large-scale ridge cultivation.
