A field survey in early June showed that the whole city

Cotton production

There are three main characteristics: first, cotton farmers have high enthusiasm for planting cotton; wherever they go, cotton farmers are fertilizing, cultivating, and preventing insects in cotton fields; two, cotton planting area is increased.

Sale

The impact of high price this year, cotton planting area increased last year, which is consistent with the results of the cotton planting area increased by 11% in the beginning of the year. Three, the growth and development of cotton is good and the growth is steady.

The average number of main stem leaves of cotton in the city is about 7, an increase of about 1 over the same period last year.

But there are also problems that can not be ignored: first, the ratio of cotton to cotton is significant, and the growth is unbalanced. The number of stem leaves of main stem after good oil is 6 to 7 pieces, and some late planted cotton seedlings are still in pformation stage, and the number of main stem leaves is only 3 to 4 pieces; two is serious grass shortage, especially oil stubble cotton fields, rape seedlings and weeds causing grass seedlings.

In view of the problems existing in the current climate and cotton growth, the current cotton production should focus on promoting root, promoting stability, promoting balance, preventing diseases and insects, fighting early and catching up.

The following six points should be emphasized:

1. Spraying on the top and following up and promoting pformation. First, spraying 1% urea and ten 0.2% of potassium dihydrogen phosphate mixture on the leaves to promote the pformation of stiff seedlings (60 thousand times better spraying the leaves on the condition of the condition, the better effect); two is the early application of fertilizer, and 3-4 kg of urea per mu.

2, loosening soil and stubble and promoting root and hair should concentrate labor, ploughing and loosening soil and stubble, eliminating hardwood and hardwood, providing good environmental conditions for cotton seedling growth and promoting root growth.

3, timely pest control

Healthcare

The main pests of cotton at present are spider mite, Aphis gossypii, Helicoverpa armigera, and bug bugs, with emphasis on red spider, especially insect resistant cotton.

We should select pesticides according to plant protection information and prevent them in time, so as to ensure the healthy growth of cotton plants.

4, clear good three ditch waterlogging prevention at present, although drought, but to prevent changes in the weather, drought to turn stains.

Therefore, combined with the application of Lei fertilizer, digging furrow and ridging the earth, digging deep trench, so that the rain can live in dry fields to prevent waterlogging.

5, the early application of bud fertilizer to build a shelf, in the middle and June in the middle of the year, combined with the middle tillage and loosening the soil, applying the bud fertilizer to achieve the combination of quick effect and slow effect, adding 30 kg compound fertilizer on the basis of the 1.5-2 side organic fertilizer, and strive to set up the high yield rack in July.

We should pay attention to the application of boron fertilizer and spray 0.1-0.2% "power boron" on the foliage of bud stage, early flowering stage and flowering stage.

6, the seedlings should be adjusted and kept stable after being sprayed. The Mu should be adjusted with 1.5-2 grams or 3-4ml, and 20 kg of water should be added to the leaf. Spray should be adjusted to 3-4 grams in the first flowering period, and 25 kg of water should be added to 6 8ml water.
