Mulberry planting technology, mulberry disease and insect pest control

1. The main points of mulberry planting technology

1. Land finishing

Flat the land and remove the debris to go deep.

There are two methods:

Comprehensive deep turn: Sprinkle soil Fertilizer or 4000-5000 kg of farm fatal Fertilizer per acre before the deep turning, and then turn 30-40 cm in depth;

Gully flip: The ditch is turned over by planting, 50 cm deep, 60 cm wide, and the surface soil and heart soil are separated. On the ditch, the soil Fertilizer is applied to the soil Fertilizer or the farm fatal Fertilizer is 2500-5000 kg.Essence

2. Plant management

planting time: December to March of the following year

Plant density and form: 1000-1200 mulberry seedlings are transplanted per acre. There are two types of planting:

Width and narrow row planting: Wide and Fertilizer conditions and flat plots are planted with width and narrow row, and triangular transplantation is transplanted.The large line spacing is 6 feet, the small line distance is 2 feet, and the plant spacing is 1-1.5 feet.

planting: Plants with poor water and Fertilizer conditions should be used for planting, such as 4 feet spacing and 1.2-1.5 feet.

3. Variety and seedling treatment

The mulberry varieties are mainly Nong Sang series, mainly Nong Sang No. 8, Nong Sang 12th, Nong Sang 14th;

Select the seedlings: separate the seedlings according to the size, plant them separately, cut off the withering root, cut the long roots before planting, and soak in the mud to improve the survival rate.

4. Plant

Miao Zheng, root extension, shallow planting and solid, should be about 10 cm into the soil of the grafting interface, and water the root water, cover the membrane (3 feet wide and width of the width, 2 feet width of the row membrane).

5. Management after transplanting

Cut: After transplanting, cut off the seedlings 5-7 inch from the ground. The winter cutting of winter planting is carried out.

Sparse buds: When the new buds grow to 4-5 inches, sparse buds, each plant is selected for 2-3 strong developmental and reasonable mulberry buds to develop strong branches.

Topping: Tool out for those who only have one bud, when the buds grow to 4-6 inches, promote its branches, and become a garden early.

Make -up: After the mulberry germination, check in time, and make a timely replenishment in a timely manner.

Dalfillery: Watering should be watered, draining watering on rainy days, and improved survival.

Strengthen weeding and fertilization: Timely cultivation and weeding in time, sprinkle buds, 10-15 kg of Urea per acre after being worn, or marshwater liquid, human feces and urine, etc., and the amount of fertilization is held in 1/3 of the Jackie Chan Sang Garden.

Second, mulberry diseases and insect pest control

1. Sanglibai powder disease

At the beginning of the disease, a white powder -shaped circular lesions were produced on the back of the blade, and then gradually expanded the connecting pieces. At the same time, the front color of the mulberry leaves became light yellow -brown;For black.This disease is mostly on the leaves in the middle of the branch, the early varieties of hardening.

Control method:

In the autumn, the silkworms are raised in batches, and mulberry leaves are first adopted.

Drought drought in the dry season to delay the hardening of mulberry leaves.

Spray the leaves at 50%todtin at the beginning of the onset, and spray it once again for 10-15 days.

2. Mulberry disease

Most of them occur in young leaves, especially in weather with high temperature and wetness and insufficient sunlight.The initial stage was water -stained sesame grain lesions, and the color was dark brown, and then expanded to nearly circular or irregular lesions.Yellow, in severe cases, the lesions are connected to each other, and the leaves are yellow and easy to fall off.

Control method:

At the beginning of the onset of the onset, the 500 times liquid or 75%methyltotobadin 1500 times liquid was used to achieve a better prevention and treatment effect, and it was harmless to the silkworm.

3. Mulberry Golden Turtle

There are many types, mainly black velvet Turtles, brown Turtles, copper green Turtles, etc.It is harmful to feeding mulberry, tender shoots and mulberry leaves with adults, and has a serious impact on the tender sprouts of seedlings.

Control method:

Use the fake death of the turtle, when the dusk is tail -to -end to eat, it will be killed.

lighting to kill adults.

When winter farming turns soil, remove the larvae and seedlings at the root of the larvae and seedlings.

In the evening, 80%of the enemy's dumb emulsion 1000 times liquid or a 50%phosphate emulsion 1000 times liquid to eliminate adults.
