1. Seedling transplanting implements sash positioning, quantitative ultra-dilution sowing, cultivation of strong seedlings, and adopting the "five-two-division two-point" supporting measures:

(1) Fine soil preparation: The seedbed land should be selected from leeward sunny, fertile land, convenient management, sandy loam soil where the former has not been planted with cruciferous crops, fine soil and no large-grained soil blocks;

(2) Pull-lined cabin: It is required to have a cabin width of 134-150 cm, a groove width of 30 cm, and a ditch depth of 25-30 cm.

(3) Sash positioning, compartmentalization, and ultra-slendering: Prepare a grid width of 134-150 cm. The grid size should be 12x12 cm. Cover the fence on the surface of the car and use the animal manure to reconcile it. Topsoil, immediately according to the grid sowing, each cell germination seed number of 1-2 tablets, after sowing with plant ash or sieve slag covered species to not seed is appropriate, pay attention to drought and drainage;

(4) Dingling in time: When the rape grows to 1-2 leaves, the seedlings will begin to be established, and the seedlings shall be kept secret and thin, leaving a robust rapeseed seedling per square. At the same time, attention shall be paid to pest control and fertilizer and water management. 3 times, pest control 1-2 times, 25-30 days transplanting;

(5) Timely spraying of paclobutrazol: spraying paclobutrazol when it grows to three leaves, to control seedling height, increase the area of ​​green leaf, increase the yield per unit area, generally paclobutrazol 15010-6-20010-6 per acre, 60 kg leaf surface Spraying.

2. High-density planting

Nakata 2040 cm; Ueda 2044 cm, and the implementation of misplaced double plant equidistant transplant, up to 1.4-1.6 million plants per acre low nitrogen high density plant technical requirements. When transplanting, remove tall plantlets, curved neck seedlings, disease and insect seedlings, and delicate seedlings. Apply root fertilizer and water while planting to ensure full field seedlings.

When planting double lines, double seedlings must be transplanted separately. The spacing between plants and plants must be 10-15 cm. It cannot be seedling seedlings, otherwise it will cause lodging and affect yield.

3. Adjust the proportion of fertilizer to achieve scientific fertilizer

Nitrogen fertilizer application time should be controlled before December, and it is best not to apply nitrogen fertilizer after December. Should adopt the "bottom foot, stable seedlings, attack disk, after the make-up" fertilizer measures:

The "bottom foot" is mainly applied organic manure, phosphorus and potash fertilizer, supplemented by nitrogen fertilizer, accounting for about 70% of the total amount of fertilizer, 1500 kg of organic fertilizer applied in Mushi, 3.4 kg of phosphorus pentoxide, 6.8 kg of potassium oxide, and 3.4 kg of pure nitrogen. Open fertilizer accounted for 28%, 2.2 kg of pure nitrogen for mu, 1.4 kg of phosphorus pentoxide, and 2.7 kg of potassium oxide;

Stable Miaofei accounted for 2%, 0.15 kilograms of pure nitrogen, 0.1 kilograms of phosphorus pentoxide, and 0.19 kilogram of potassium oxide.

The above two fertilizers must be applied before the year.

The "supplement" is mainly based on micro-fertilizers. In the early stage of Yanghua, the mu was sprayed with 0.1% boron fertilizer solution and 0.1% potassium dihydrogen phosphate solution. After spraying, it was sprayed once at the end of the flowering stage. Spray 60 kg of fertilizer, can play a role in full-grain weight gain.

4. Strengthen management

During the seedling stage, attention should be paid to the drainage of the gullies, control of pests and diseases such as aphids, cabbage caterpillars and downy mildew, cultivating and weeding 1-2 times or chemical weeding once. In the middle and late stages, it is mainly anti-disease-resistance, timely removal of force, deterioration of the disease environment, early use of carbendazim and other pesticides to control sclerotial sclerotia, drought occurs after the end of the flower, to be properly watered drought, and can be used urea 0.5 kg, Potassium dihydrogen phosphate 0.1 kg water 100 kg spraying plants to prevent premature aging.

Amino Acid is a compound in which a hydrogen atom on a carbon atom of a carboxylic acid is substituted with an amino group, and the amino acid molecule contains two functional groups, an amino group and a carboxyl group. Similar to hydroxy acids, Amino Acids can be divided into α-, β-, γ-...w-amino acids according to different positions of the amino group attached to the carbon chain, but the amino acids obtained after protein hydrolysis are α-amino acids, and There are only twenty, they are the basic units that make up Proteins.
Amino acids are the basic substances that make up the protein needed for animal nutrition. It is an organic compound containing a basic amino group and an acidic carboxyl group. The amino group attached to the α-carbon is an α-amino acid. The amino acids constituting the protein are mostly α-amino acids.
Amino acids can exert the following effects through metabolism in the human body: 1 synthesizing tissue proteins; 2 converting into ammonia-containing substances such as acids, hormones, antibodies, creatine; 3 converting into carbohydrates and fats; 4 oxidizing into carbon dioxide and water and urea, generate energy
