High-yielding Cultivation Techniques of Live Dry Rice in Summer

The city introduced upland rice cultivation in 1997. Over the past four years, the city has grown rapidly and its area has continued to expand. In 2000, the planting area reached 29.8 million mu, which was broadcast in summer. The average per mu yield was 346.4 kg of early rice, which was 150 yuan more than the average yield of summer corn in the same season. Not only increased the income of farmers, but also solved the problem of a large area of ​​the local shed and shortage of materials for grasshoppers, which provided a new direction for the adjustment of the planting structure of the original grain production area in our city. The high yield cultivation techniques are summarized as follows:

One, planting mode

Upland rice is planted in our city with “wheat-early rice” as its main planting pattern. In addition, two efficient modes of cropping, “potato-upland rice” and “onion-upland rice,” are adopted. The city grows 100,000 mu of potatoes and 15,000 mu of green onions. Potatoes are usually planted in mid-March and harvested in early June. Round onions are usually sown in late September and planted in early November and harvested in mid-June. The last two modes of planting dry rice, good rinsing, and early sowing date are conducive to the live and high yield of upland rice in the summer.

Second, species selection

In the past four years, we have tested Brazilian upland rice IA-PAR-9, upland rice 277, upland rice 11, upland rice 65, upland rice 297, drought overhaul 2 and Danjing 8, etc., and have selected Brazil upland rice IA. -PAR-9, Early Rice 277, Upland Rice 297 Three varieties suitable for planting in our city:

1. Brazilian upland rice IAPAR-9: The strongest drought resistance and the highest yield potential. We achieved 513.4kg per mu in high-yield research in 2000, but the plant type was high (120cm in plant height) and the lodging resistance was relatively poor. Longer growing period, in our city summer broadcast 110-120d, suitable for spring broadcast or grab live summer broadcast.

2. Upland rice 277: Strong drought resistance, high yield levels, resistance to lodging, summer growth period is generally about 105d, suitable for summer harvest after wheat harvest.

3. Upland Rice 297: Good quality, strong drought resistance, and lodging resistance. The yield level was slightly lower than that of Dry Rice 277, and the growth period of summer sowing was 105-110 days. Summer sowing in our city can be normally mature and the comprehensive traits are the best.

Third, high-yield cultivation techniques

1. Fine sowing: Most of us use artificial trenching and sowing, but also a small amount of mechanical sowing, the average spacing 25cm. Seed use per acre: Brazilian upland rice IAPAR-9 is 3-4 kg; upland rice 277, upland rice 297 is 6-7 kg. If a large area is planted, mechanical sowing can be used, and the wheat sowing machine has good sowing effect.

Before seeding, the seeds will be dried, soaked, and seeded with a series of treatments. After drying for one day, soak in seeds with warm water at 40°C for 12 hours, then sterilize with 300 times carbendazim for 12h; sterilize the seeds after rinsing with clean water, then soak in fresh water for 24-48h, pay attention to changing water, and wait until the seeds are white Remove and air dry; when dry, use 50% phoxim or 50% methyl iso-phosulfite to prevent and control underground pests. The dosage is 0.2%-0.3% of the seed amount.

During the sowing period, it is best to ensure that the broadcast is completed before June 20, and the sooner the better. When sowing should pay attention to enough planting, lack of lyrism must be sown.

2. Scientific fertilization: According to the characteristics of the early rice need fertilizer: production of 500kg rice requires N: 10.4kg; phosphorus pentoxide: 4.8kg; potassium oxide: 12.8kg. According to different fertilizer effects, formula fertilization. Take the principle of applying basic fertilizers and fertilizers by stages.

Combining land preparation with 3,000 kg of organic fertilizer, 35 kg of ternary compound fertilizer (15-15-15), 15 kg of potassium sulfate and 2 kg of zinc sulfate as base fertilizer.

Fertilizer is generally divided into two phases: First, before the delivery, Mushi urea 5-10kg; Second, in the jointing period of a booting, Mushi urea 5kg.

3. Chemical weed control: Weeding is an important link in the production of upland rice. According to our experiments in recent years, the special rice remover No.1 and Nongsi have a good weed control effect in the production of upland rice. The method of application is uniform spraying prior to emergence after sowing.

4. Plastic film cover: Plastic film can significantly improve soil drought and shorten the growth period. In 2000, we conducted a test with an area of ​​3.6 mu and an average yield of 442.5 kg per mu which was 368.2 kg higher than that of the control and an increase of 20.2%. The effect was obvious. The rice film covering method of the upland rice is similar to that of wheat, with a film width of 90 cm and a thick film of 4 lines. The use of hole sowing, hole 15cm, 7-9 per hole.

5. Field Management: (1) Watering. Although the drought resistance of dry rice is strong, it must be watered during drought, especially the booting flowering period is the water-sensitive period of dry rice. In this period, drought can easily lead to increased empty grains. This must be taken seriously. (2) Pest control. The main control objects were rice fieldworms, leafhoppers, rice planthoppers, rice blast, and sheath blight. The rice field aphids are mainly rice leaf roller, leaf borer, and rice stem borer. In the past two years, the incidence of rice leaffolders and stem borers in our city was heavier. Rice field locusts can be sprayed with 40% or 20% high-permeability methamidophos EC and 1500 times evenly sprayed, and can also prevent pests such as leafhoppers and rice planthoppers; 20% tricyclazole can be used for rice blast. 75-100g of water to 75kg spray, or 50% mancozeb 600 to 800 times, with 50% carbendazim 500 times spray control; Sheath blight available 70% thiophanate-methyl WP 100- 150g water 50-100kg, or 50% carbendazim powder 100g, with 20% Triadimefol 50ml, 50kg spray control of water.

This instrument is used for docking the tails of newborn piglets and lambs.

  • The hot knife will remove the tail and cauterize the wound at the same time, dramatically reducing the incidence of infection
  • Approximately 60 minutes operation from a full cylinder
  • Included: knife, cylinder (empty) and holder
  • also we have different type of piglet tail cutter .
