When does rice spread foliar fertilizer?

A group of farmers in Guanjiayuan Village, Xingfu Township, Gangzha District, Nantong City groped in their own 40 acres of loose rice.

flat

The average yield per mu is 700 kilograms. This is more than the traditional transplanting, throwing and drilling of rice.

150kg ~ 250kg。 Spreading rice saves seedling transplanting, and the water consumption is three times that of other planting methods.

One third, the cost is also less than other planting methods 100 yuan.

To popularize rice, we must master its characteristics, and pay attention to fertilization, land leveling, sowing, chemical weeding and plant diseases and insect pests.

High yield can be obtained by cultivation and management techniques such as pest control and field scaffolding.

First, fertilization technology

In the whole growth process of rice, attention should be paid to basic fertilizer and adequate fertilization at seedling stage and early stage. Not advocated in the middle and late stage

Fertilize. Apply a small amount of fertilizer when it is particularly yellow in the middle and late stage. Apply foliar fertilizer once before rice is broken.

1. Before cultivated land, base fertilizer refers to organic fertilizer, such as human manure of not less than 20 tons per mu; or

Sheep manure, cow dung and other fertilizers shall not be less than 10 ton per mu.

2. After the land is initially leveled, at least 35 kilograms of base fertilizer and organic fertilizer (such as rapeseed cake) should be applied per mu.

Gold; Ammonium bicarbonate and compound fertilizer are not less than 25 kilograms per mu. It is very fat in shallow water.

3. After sowing 18 ~ 20 days, apply the second tree fertilizer before the first water inflow is about to dry out. Shi haofa

The tree was removed after fertilization. Urea and compound fertilizer are 25 kilograms per mu. Silicon fertilizer is 5 Jin per mu. rapeseed cake ［usu used as a fertilizer］

Not less than 35 kilograms per mu.

4. Rice must be fertilized before booting stage 15 days. When the water in the field is almost dry, use urea and compound fertilizer per mu.

Sprinkle 25 kilograms of fertilizer evenly.

5. Laying rice, especially Huang's in the middle and late stage, should put the fertilizer down early before booting stage. Progress and breakthrough

After the belly, it is not suitable for fertilization. At this time, fertilization is easy to cause rice lodging; Second, the particles are not full; three

It is to promote the rice to turn green in the later stage.

6. Before sowing rice, there should be a foliar spray with 7.5g and 50kg of water per mu.

Spraying evenly is beneficial to increase the 1000-grain weight of rice.

Second, the paddy field leveling requirements

The paddy field has been initially leveled by plowing and harrowing, and it needs to be leveled again after applying base fertilizer, so that there are no pits in the field.

It is forbidden to run against the current in the protruding part of the depression to prevent Takaizumi.

Third, the main points of sowing

1. Seeds and seed quantity should be selected, and they should be dried in the sun without mildew; The amount of seeds used per mu is one.

It's usually 8 kilograms. If the fertility is insufficient, the yield per mu should be increased after June 12 this year 1 kg.

2. Sowing time When sowing rice this year, we should strive to sow from May 22nd to May 3rd1. at the latest

No later than June 15.

3. Sowing step (1) After the paddy field is leveled for the second time, it should be planted in muddy water, that is, muddy water.

(2) seed soaking method/kloc-soaking seeds in paddy fields 0/2 hours ago is called advanced method, which can germinate in advance. paddy field

Soaking seeds while plowing and harrowing is called synchronous method, and there will be no rotten buds after seeds enter the field, compared with advanced methods.

It belongs to delayed germination. Compared with dry direct seeding rice, these two methods are superior to dry direct seeding rice under the condition of synchronous sowing.

Buds germinate 2 ~ 3 days in advance. (3) Take the seeds out of the water to dry, and then weigh them. Divide fields, if

The amount of seeds used in each dry aliquot. (4) Divide the site into several equal parts and divide them on both sides of the rope.

Every equal portion. (5) Finally, the seeds of each equal part are directly and evenly scattered in the field along the rope direction. homomorphic

Push until the sowing is over.

Fourth, chemical weeding and pest control.

1. The first chemical weeding must be carried out on rice from the date of sowing 1 days later. Thinking with agriculture is evil grass.

The dosage of pesticide is per mu 100g ~ 150g, diluted with 50kg of water and sprayed evenly. No leakage is allowed.

2. After rice is sown 18 to 20 days, the second chemical weeding should be carried out when the rice is first watered. moisturize

The time is five days. Pesticides are still used, and the dosage per mu is 100g. After mixing with soil or rapeseed cake, spread it evenly in the ground.

The leaking water must be re-sprayed.

3. The first control of rice diseases and insect pests from 7 days after sowing to 10 day.

4. Rice diseases and insect pests should be controlled for the second time within 18 ~ 20 days after sowing.

The second drug is diluted evenly with 40 grams of metronidazole per mu, 50 grams of iprodione per mu and 50 kilograms of water.

Spray.

5. The control of other pests and diseases is basically the same as that of dry direct seeding rice. There are two more points to note. ( 1 )

The dosage of pesticides per mu of sowing rice should be 50 g ~ 100 g more than that of dry direct sowing rice. This is because it is better than dry direct seeding rice.

There are more than 50% rice in the same area. (2) The best time for the last application of pesticide to rice,

This medicine should be used before the stomach breaks. On the contrary, it will cause more withered seeds and less full seeds.

Five, shelving skills

Spreading rice requires the technology of releasing fields during the whole growth process, which is not suitable for wading for a long time. Aside from the field.

Research skills, the main points are as follows:

1. From the date of sowing, there is water to be drained from the field. It takes 18 to 20 days for the first entry.

Water. Don't store water before this.

2. The first water inflow is 5 days, and the second water inflow can be started after 7 days to 10.

3. From the time of sowing, after 35 days, that is, from seedling stage to booting stage, the principle of water inflow is to water in advance.

Go to the field, let the water in the field dry every 3 to 5 days, and then dry every 3 to 5 days before entering the water.

Ask the fields not to sink their feet. This cycle is repeated until the end of this stage.

4. From the booting stage, before and after the broken belly, to the full heading stage, the principle of water inflow is not only the above seedling stage.

In addition to this startup stage, you can also go into shallow water on the first day, drain the water in the field the next day, and then dry it.

Take the same method and feed water every 3 ~ 5 days. This field still doesn't need feet.

5. Within 40 days after full heading, the principle of water inflow in this last stage is water inflow on the first day and drainage on the second day.

After drying, add water every 3-5 days. It is not advisable to work hard in the wild. If there is foot sinking, it must be taken.

Extend the interval until the end.
