How to play the advantages of multi-stalk cotton never gossiping
Happy plant type multi-stalked cotton has the advantage of never going crazy, how to create a happy type of multi-stalk cotton, which is the key to multi-stalk cotton three-dimensional high-yield cultivation techniques. The preferred accessory species for multi-stalked cotton is the insect-resistant hybrid cotton of the chicken paw leaf. The growth and development of insect-resistant hybrid cotton of C. edodes is fast, such as inverted umbrella cultivation, leaf branches, fruit branches are preserved, the main stem, leaf branches are topping up prematurely, or the seedbed is topped for picking, forming a double stalk cotton or triple stalk cotton, Branches are too early to be topped, middle and late roots are over-dressed, and then they are exposed to rain. Fertilizers hit the heads of hair, cotton plants grow madly, and buds grow wildly. The physiological shedding of the buds must be serious; The three fruit branches, their resistance to insects was reduced, fulfilled the "insect-resistant cotton is not insectless cotton", in the blind cinerea, cotton bollworm, Spodoptera littoralis major years, not only poor insect resistance, but also the introduction of harm and The moth lays eggs, causing an outbreak of insects and shedding of a large number of larvae. The measures are: (1) To emphasize Daejeon's top. Cotton seedlings were transplanted for the first time a month after they were transplanted and planted with 8-9 true leaves, and they were cultivated into 4-6 robust branches with happy plant type multistalk cotton. Practice has proved that such a truly multi-stalked cotton is not afraid of fertilizers and waters, never mad, and has a balance between vegetative growth and reproductive growth. (2) Use early maturity worms. After the multi-stalked cotton of general broad-leaved varieties solved the problem of avoiding rotten peaches in August, the insect-resistant multi-stalked cotton of the narrow-leaf species had further solved the problem of avoiding rotten peach in September. The following main attack goal is: how to make full use of the first element of early maturing, high yield, high quality and resistance to insect pests in the insect resistant hybrid stalk cotton, to solve the problem of avoiding the pest in the period from August to September. The problem is to make a fuss around "premature" and then use its high yield, high quality, and resistance to various traits. Specific measures: (1) Fertilize at the end of a chase. At the end of the fertility, apply 50-100 kg of nitrogen, phosphorus, and potassium compound fertilizer per acre; apply fertilizer to 50-100 kg of urea per acre, and finish top dressing before the end of June. That is, the field saw the top dressing for a suitable period. At the discretion of the middle and late foliar spraying potassium dihydrogen phosphate. (2) The key is twice topping. For the first time, the main stalks were towed at one time in Daejeon around June 15 of the seedling stage to create happy plant type multi-stalk cotton. Twice topping is the first time you destroy the branches. Branching is too late to premature aging, prone to premature buds. It will be more timely when branches are to be towed around July 25. In addition to these two toppings, the entire growth period did not prune, retaining all the leafy branches, letting the survival of the fittest naturally grow without hitting the top of the colony. Even if there were axillary buds, the buds were not wiped off. In the balance between vegetative growth and reproductive growth, as much as possible to retain all the functional leaves on the multi-stalked cotton plants in order to facilitate photosynthesis, production of nutrients, promote the top of the peach, add fruit and fruit branches three times late autumn peach. Such as fine pruning, anti-prone to premature aging. (3) mulch film coverage early. Generally invested tens of yuan per mu, can increase hundreds of yuan early harvest. Pay attention to removing the film as soon as possible after the rainy season, so as to root the Department.
