Strictly implement the seed structure and season

It is already early May, if in previous years, at this time the spring rice has been flowering, this year, due to the prolonged cold weather, the rice plants have just started to form ears. Therefore, the time for summer-autumn crop production is very limited.

In addition to difficulties in electricity, water, and rising material prices, solving the seasonal problem is considered one of the decisive solutions to a successful summer-autumn crop.

Based on the actual situation, the agricultural sector has determined the safe harvest time frame for the summer-autumn crop. Specifically, about 23,600 hectares of flooded summer-autumn areas (concentrated in Dien Chau, Yen Thanh, Quynh Luu, Nghi Loc, Hung Nguyen) must be harvested before September 5; intensive summer-autumn areas must be harvested no later than September 15.

In fact, after 28 years of summer-autumn rice production in Nghe An, it shows that to ensure safety before the flood season, the rice variety structure in this crop must be as short-term as possible, and planted as early as possible.

Therefore, with more than 23 thousand hectares of flooded summer-autumn rice, it is advisable to plant rice varieties with a growing period of less than 100 days such as pure rice varieties Vat Tu-NA1, glutinous rice 352 and some domestic hybrid rice varieties such as Viet Lai 20, Viet Lai 24...

Currently, about 685 tons of rice varieties with a growing period of less than 100 days have been imported, of which about 400 tons are hybrid rice (including Viet Lai 20, Viet Lai 24, Q.uu 6, PAC 807) and 285 tons are pure rice (including NA1, PC6, and 352 glutinous rice). Suppliers can also import some new short-growing varieties that are allowed for trial production such as QR1, Thien Uu 128, Thien Uu 998, etc. if localities have plans to register early.

For highland areas and areas less prone to flooding, it is possible to use high-yield rice varieties with a growing period of less than 110 days such as Q.uu 1, Khai Phong No. 7, pure rice varieties Vat Tu-NA2, Dac Uu 11, Thien Nguyen Uu 16, Huong Thom No. 1, Bac Thom No. 7, Nep 97, Nep 87, etc.

Pay special attention to these areas, if late planting is required, use short-term varieties according to the structure of flood-prone areas. Particularly in localities with high land and rarely flooded, with conditions for intensive farming, in addition to the above varieties, rice varieties with both high yield and good quality should be used to increase production value such as Q.uu 6, Bio 404, Nhi uu 838, Kim uu 725...

According to agricultural experts, this year spring rice will bloom on May 20-25 and be harvested from June 20-25, while the normal safe crop time frame is to sow before June 5 and harvest before September 10. Therefore, it is necessary to transplant old rice seedlings to take advantage of the time for the rice plants to grow and develop. Director of the Department of Agriculture and Rural Development - Mr. Nguyen Tho Canh said:

This year, due to the stressful season, if you want to avoid flooding in the summer-autumn rice crop, you absolutely should not sow directly, because that will delay the crop by 15-17 days and it will be impossible to avoid flooding during the rice ripening and harvesting period.

The province has now decided to support funding for purchasing seed treatment chemicals (50% support for the plains and lowland areas, 90% support for the highland areas, and 100% support for purchasing pesticides to spray on seedlings when there is a planthopper infestation or 2-3 days before planting), so localities and farmers must thoroughly carry out seed treatment and spraying to control planthoppers according to the instructions of the Plant Protection Agency.

In particular, to ensure harvest on time, seedlings must be sown on hard ground or drained when seedlings have enough leaves to be transplanted and the soil must be prepared carefully to transplant old seedlings to help the seedlings not be damaged during transplanting and recover quickly. The number of seedlings in a clump and the number of clumps on an area must be increased depending on the quality of the soil and the amount of fertilizer investment.

In addition, localities need to direct farmers to focus on heavy basal fertilization before planting, on average 4-5 quintals of manure, 25-30 kg of NPK 8-10-3 fertilizer and 3 kg of urea/sao. After ten to twelve days of planting, continue to apply 13-15 kg of purebred rice varieties and 15-17 kg of NPK 15-5-20 fertilizer for hybrid rice varieties./.
