The management of water in the field is quite important. If there is a lack of water, the rice plants will be barren and not grow. Too much water will cause the plant to stagnate and die. Therefore, the stage of water management needs to be paid attention to.

First, it is necessary to leave a shallow amount of water about 3-5cm after planting to help the rice take root. This amount of water also creates favorable conditions for rice to branch, keep plants moist against hot sun and combine plant protection with pesticides and weeds.

Next, at the tillering stage, you keep the amount of water in the field about 1-2cm for the best growth. If the amount of water in the field is too high, it will make the plant weak and easy to rot.

At the end of tillering, you let the water drain out to dry the field. Drying time is about 1 week.

  1. Trim miles to ensure density

Immediately after transplanting, it is necessary to check in the field if there is a loss of space, it should be trimmed immediately to ensure density. The crop at the time of pruning ends up to 7 days after transplanting.

  1. Fertilizer technique:

– Need to fertilize the balance between nitrogen – phosphorus and potassium.

– Fertilize at the right time, implement the motto of heavy first, light last, should not apply nitrogen late to make the plant grow too strongly in later stages.

– The amount of fertilizer and the stages of application depending on the soil can be used:

– Amount of fertilizer for 1 sao of Northern Vietnam (excluding the amount of primer): 15-17kg of NPK (12.5.10); Add 2kg of urea nitrogen; 1.5kg Potassium chloride; Divide fertilizer times:

+ Top dressing 1: When the rice takes root in green anise 10 kg NPK (12.5.10) + 2 kg urea nitrogen;

+ Topical fertilizer 2: Fertilize larva when rice has cockroach droppings: 5-7kg NPK (12.5.10) + 1.5 kg Potassium chloride.

Attention: For crops, foliar fertilizers should not be applied, unless it is used to treat diseases. Fertilizer should be applied in the early morning and late afternoon when the weather is cool. It is recommended to use synthetic fertilizers.

  1. How to prevent pests:

– Do not apply too much nitrogen fertilizer, causing excess nitrogen will cause rice to tire, fall prone to pests and diseases. Need to fertilize the balance of nitrogen – phosphorus – potassium.

– Follow up the estimated news, forecast the situation of pests and diseases and the direction and guidance of prevention in each period of the authorities in Vinh Phuc province through the combined mass media. with regular visits to the fields to detect pests and diseases in time and take measures to deal with them. From this period to the end of the season, pests and diseases often appear on winter rice such as: yellow apple snail, leaf roller, stem borer, brown planthopper, bacterial stripe disease, leaf blight, yellow leaf disease physiologic…

Conduct additional foliar spraying of fertilizer. One of the types of Komic, Buffalo Head 502, VP01 can be used to provide nutrients to help rice plants recover quickly. When rice is diseased absolutely should not apply nitrogen. After seeing that the rice has recovered from the disease, farmers can proceed to take care of the rice as usual.

  1. Rice harvesting techniques

Harvesting rice is also based on experience and timing. You should check, if you see that the number of golden seeds accounts for over 90%, you can gradually harvest them. Can be harvested after blooming from 28-30 days.

It is recommended to use a row harvester to cut rice. After cutting, proceed immediately, do not dry the bunches in the field. Use a vertical threshing machine (thresher, threshing machine) to thresh rice.

  1. How to preserve wet rice?

In the winter-spring crop, dry the rice on a brick, cement or earthen patio. It is recommended to use nylon netting under the drying process, drying for 2-3 days is okay.

In the summer-autumn crop, use a vertical column dryer STD-1000, a horizontal griddle dryer or a drying tent combined with a ventilation fan SLQ-2000 to dry the rice.

After drying, rinse and use the bag to store. Store rice in a cool and dry place. If stored for less than 3 months, the moisture content of paddy reaches 13-14%. If the storage time is more than 3 months, the humidity should be below 13%.

Above is information on planting and caring techniques for rice. Hopefully they will have more experience to have a bountiful harvest.
