What is rice live broadcast? Rice direct seeding technology refers to the planting method of directly planting seeds in the field for cultivation. It can be divided into four types: direct water, dry live, wet live and dry rice. This technology can not only increase rice yield, but also increase economic benefits. It can also make the content of trace elements in rice planted high, so today Xiaobian will briefly talk about the advantages of rice live broadcast and high-yield cultivation techniques.
First, the advantages of rice live broadcast
1) Labor saving (3-4 labors per mu), labor saving (saving labor costs 200-400 yuan), high labor productivity (up to 1.5 times).
2) This technology can make rice early, and can effectively shorten the growth period of 5-7 days.
3) It does not occupy the farmland, which saves the working hours and is conducive to expanding the planting area.
4) Compared with transplanted rice, the input and output per unit area of ​​direct seeding rice is 22.35% higher, which has the advantages of high input-output ratio and good economic benefits.
5) It is conducive to the development of scale operation, which can alleviate the contradiction of seasonal tension of labor, and is also conducive to mechanization and mechanization. It has important application value for large planters and large and medium-sized farms.
Second, rice high-yield cultivation techniques
1) Preferred varieties
Select high-yield, high-quality, wide-suited, multi-resistant hybrid mid-season rice and conventional rice with a growth period of about 135 days. For dry and water-deficient fields, you can choose upland rice varieties; today's large-scale demonstration and promotion varieties include Anliangyou 318 and II You 851. Biffeng No. 1, Zhongnong 2008, Lukhan No. 1, Yuyu No. 3, Yuyu 209, etc.
2) Grab the seeds at the right time
Sowing in early June, sowing at the latest on June 20.
3) Farming methods
After harvesting the wheat, the straw can be cleaned in time. The land can be no-till, rotary tillage, and plough. At the same time, it is necessary to go to the land to level and fine, and open the side ditch. The width of the kneading surface is 4 meters.
4) Seeding method
If conditions permit, you can use machine-casting, or you can use hole-casting, strip-casting, and artificial spreading; seeding amount: about 2.5 kg per mu of hybrid rice, 6-8 kg of conventional japonica rice, 8-10 kg of conventional japonica rice, 8-10 kg of upland rice; sowing Pre-management work: Excavating rice seeds for 1-2 days before sowing, then soaking seeds for sowing, dry water is soaked in water after sowing, in order to fight for early seedlings, even seedlings, strong seedlings, and whole seedlings; soaking seeds are soaked with special soaking seeds for rice live broadcast, The rice seeding special soaking agent is made up of the following parts by weight: 100 parts of magnetized water, 5 parts of selenium-enriched yeast, 2 parts of purple sweet potato anthocyanin, 3 parts of coagulated polysaccharide, 2 parts of curcumin, 5 parts of alanine. 4 parts of pepper water extract, 4 parts of carbendazim, 2 parts of seaweed powder, 5 parts of water-soluble potassium, 2 parts of corn peptide, 2 parts of chelated iron, 0.5 part of sweet peptide, 1.5 parts of phosphate buffer, medium 0.5 parts of protease and 2 parts of corn starch.
5) Fertilization
Apply the base fertilizer, apply 40-50 kg of compound fertilizer and 8-10 kg of urea once; the compound fertilizer is made up of the following parts by weight: 100 parts of farmyard manure, 5 parts of loach, 5 parts of moss, and biogas residue. 5 parts, 50 parts of phosphate fertilizer, 5 parts of sodium selenite, 20 parts of ammonium sulphate, 5 parts of mulberry leaf ash, 5 parts of pepper leaf ash, 15 parts of straw powder, 10 parts of water-soluble potassium, 4 parts of rooting powder, bamboo powder 2 2 parts of tea ash, 4 parts of distiller's grains, 5 parts of fungicide, 5 parts of sea mud, 2 parts of potassium dihydrogen phosphate, 2 parts of pine balls; fungicides are made of the following parts by weight: sodium nitrophenolate 3 parts, 10 parts of permethrin, 10 parts of zebra zebra, 5 parts of dried peppermint powder, 3 parts of purple yam dry powder, 1.5 parts of curcumin, 5 parts of chrysanthemum powder, 1.5 parts of matrine, glyceryl behenate 2 parts, 0.5 parts of tea extract, 2 parts of eucalyptus bark, 1.5 parts of benzoic acid, 1 part of brassene, 1.5 parts of saponin, 0.5 part of naphthaleneacetic acid, 0.5 part of coumarin, and 1.5 parts of camphor powder.
6) Scientific management of water
Before the sowing, the scorpion is kept in the front; before the booting, the drought is mainly used to control the tillers, and the roots are prevented from lodging under the roots; the diving layer is kept from the booting to the half month after the heading; after the milk is cooked, the water is released and the field is harvested early, so as to strive for early harvest.
7) thickening and diarrhea
In the 3-4 leaf stage of the seedlings, check whether there is a lack of seedling monopoly in the field. If there is, it can be thickened and diluted.
8) Weed control
The herbicidal strategy is mainly based on spraying soil-blocking treatment agent, supplemented by stem and leaf treatment agents, and artificial extraction.
9) Pest control
Based on the information on pests and diseases of local plant protection stations, focus on the prevention and control of rice smut and rice planthopper;
10) Harvest at the right time
When more than 90% of the rice grains are yellow, they need to be harvested in time to facilitate autumn seeds.
